Question 1

What is a Photovoltaic Solar Energy System?

Accepted Answer

It is a set of advanced technological components that takes advantage of the sun's energy to produce electrical energy for its safe use, whether domestic, commercial or industrial.

Question 2

What components does a Photovoltaic System have?

Accepted Answer

The basic components of a photovoltaic system are:

Solar panels
Power inverter
Batteries
Battery Controller
Thermal switches
Cabling
Support structure
Internet link
 
Note: Not all photovoltaic systems are integrated by all the components since this will depend on what type of system is required according to the needs

Question 3

What types of Photovoltaic Systems are there?

Accepted Answer

There are three types of photovoltaic systems, depending on the components used. These are divided into systems that are connected to the local power grid, with or without batteries, and those that are not connected to the local grid (CFE). They are called grid-tied (interconnected), hybrid, and off-grid (stand-alone) systems, respectively.

Question 5

With a Grid-tied PV System, will I have power if the local power grid goes down?"

Accepted Answer

No, for technical and safety reasons. However, this can be prevented by installing a system with battery backup, known as a hybrid system.

Question 6

Can I have batteries in a grid-tied PV system, and what are they used for?

Accepted Answer

Yes, it requires the selection of suitable components for this and it gives you the support in case the local network has a service outage

Question 7

When is it advisable to choose a system with batteries?

Accepted Answer

It is recommended to include batteries with your system if you do not have, or do not wish to have, a connection to the local power grid (CFE). Batteries are also recommended if, even with a grid connection, you need backup power to avoid outages. In grid-tied systems, when the local grid service is interrupted for any reason, systems without batteries automatically shut down due to safety regulations.

Question 8

What is an Off-grid Photovoltaic System for?

Accepted Answer

They are usually to supply moderate energy demands, in most cases in remote communities with no access to the local grid (CFE).
They are regularly integrated with batteries and in some cases without them, such as for daytime equipment such as irrigation pumps, etc.

Question 9

Is a Photovoltaic System expensive?

Accepted Answer

It is very cheap if you consider that, depending on your current rate, it is like paying 1 to 4 years of energy in advance so you do not have to pay it again in the next 25 years.
 
Of course, it can be considered an important investment that will depend directly on the amount of electricity you require. In any case, you start receiving the benefits from the first month.

Question 10

How long does a solar panel last?

Accepted Answer

The waranty covers the function of the panels for 25 years but the real life of a panel of good quality is between 35 and 45 years depending on atmospheric conditions such as the intensity of solar radiation and salinity in the environment.

Question 11

How much does a panel cost?

Accepted Answer

It is a very common question, however, we do not sell panels separately but turnkey systems that include calculation of needs, design, installation, procedures with CFE and all necessary components such as power inverter, structures, wiring, etc.
We invite you to contact us (javascript:void(0))to request a personalized and specific quote to your needs.

Question 12

What is a power inverter?

Accepted Answer

It is a key and basic component for your system being this the central computer or brain of the system. This fulfills the functions of converting the energy coming from the panels into direct current (DC) and transforming it into alternating current (AC) where at the same time, for interconnected systems, it synchronizes it with the current coming from the CFE network into parameters such as voltage and frequency.

Question 13

How long does a power inverter last?

Accepted Answer

This will depend a lot on the inverter selected for your equipment, but a good quality one should last at least 10 years.

Question 14

How much can I save?

Accepted Answer

You can get a monthly savings of up to 99% of your current electricity cost depending on several factors such as:
 • Current consumptions
 • Current and residual rate with CFE (residential, commercial, industrial, agricultural irrigation, etc.)
 • Available spaces for installation.
 • The capital you want to invest.
We invite you to contact us (javascript:void(0))to give you an accurate analysis of your savings expectation.

Question 15

How do I know if I should buy a system?

Accepted Answer

If your interest is environmental, convenience is absolute in all cases.
 
If your interest is economic savings, the first thing you should consider is the current cost of your energy since currently some CFE rates have significant subsidies making them very competitive such as subsidized residential or 01, agricultural for water extraction or industrial among other. This can make the return on your investment be extended to many years reducing economic convenience.
It is very convenient for you if you are in a residential high consumption, commercial rate or if you pay more than $ 2,000 bimonthly pesos.
Also if your rate is residential with subsidy but you are about to install air conditioning or plan to increase your consumption considerably with some electronic equipment.

Question 16

What warranties are offered for a photovoltaic system and its components?

Accepted Answer

Each component of the system comes with its own specific warranty. The photovoltaic panels include a 10 to 12-year warranty against manufacturing defects, as well as a 25-year performance warranty, guaranteeing at least 80% of their original capacity at the end of that period.
Inverters typically have a 5-year warranty, with the option to extend it up to 10 years. The installation work is covered by a 2-year warranty.
Batteries also come with warranties that vary depending on the type and technology selected.

Question 17

How many panels do I need?

Accepted Answer

This should be determined through an in-depth analysis where we must consider the geographical location of your property as well as your energy requirements which we can do by reviewing the history on your current energy bill with CFE.
 
Contact us (javascript:void(0))to perform a calculation and define the best option to meet your needs.

Question 18

What happens if my property is new or I have no history of consumption?

Accepted Answer

Do not worry, although we will require a slightly more complex method where we must contemplate all the charges (electrical equipment) and calculate their use time as well as the amount of energy each consumes.
 
With our advice we can identify your needs as well as the system that suits you. Contact us (javascript:void(0))to provide personalized advice.

Question 19

Can I increase or decrease the size of my equipment at some time?

Accepted Answer

Yes, because the equipment is modular you can increase the size and production capacity of your system at any time if the space and conditions of the system are adequate.
 
You can also reduce the size of your equipment if you decide, but for this you must consider the technical conditions of your power inverter to ensure its proper functioning. If feasible you can get to use your removed panels to integrate another system and use it in another building where you may have to complement it with the missing components for its installation and proper operation.

Question 20

Can I combine types and brands of panels?

Accepted Answer

It is not recommended for new installations but in the extensions it is possible and it can become 100% functional with the proper advice, calculation and components.

Question 21

Can they be installed in my company or is it just for my house? (or vice versa)

Accepted Answer

We can install it anywhere, we are specialists in integral systems for any type of electricity consumption and based on your needs we offer you the best option for you to live and / or functions with solar energy.

Question 22

How does it work when the Photovoltaic System is connected to the CFE grid?

Accepted Answer

We take advantage of the grid as a storage system to inject the surplus energy produced during the day by the photovoltaic solar system and be used at some other time or season, such as nights or winter with heaters or summer with air conditioners.
In this way and if you currently do not have problems of constant power outages or for long periods of time, we could avoid the use of batteries as a component of the system since they are expensive and would be the component that would require replacement in a shorter period of time. around 5 to 8 years old.
When we install your system, we will carry out a series of procedures with CFE where your current meter will be replaced by a bidirectional one that measures the current that enters as well as that which leaves your property. In this way, CFE will continue to send you its receipt periodically in which you can check your balance and identify how much energy you have accumulated.
This service with CFE has a cost that goes from $ 25 pesos per month and can increase depending on your rate (residential, commercial, industrial, etc.) as well as if you exceed your energy consumption in relation to the production of your system.

Question 23

What happens if I require more energy than calculated to be produced by my system?

Accepted Answer

Since your property is interconnected to the CFE network, if you require more energy from that produced by your system or stored as yours on the network, you will automatically be provided with CFE energy. You should consider that this additional energy will be charged to your receipt and you will have to pay it according to the corresponding rate of CFE or local supplier.
If this becomes constant, you can choose to expand your team by adding as many panels as you need.

Question 24

Does the CFE buy me the energy I produce?

Accepted Answer

As of January 2017, it is possible due to the new regulations, although there have been delays in the application of this scheme caused by disagreements between the sale and purchase prices of energy.
 
What we recommend is to stay in the old scheme that allows the net balance in kWh (Energy Units) since it is accounted for in an equal exchange of ONE TO ONE, this means that what you deliver is returned to you with the same value.
 
In the CFE charging scheme, the balance is made in pesos and different values are considered for the energy injected as well as for the energy extracted from the network. This must be well understood so that you find benefits since you must produce more energy than you actually use so that the surplus produced by your system and injected into the network generates enough credits to cover the cost of your consumption and thus generate additional income.

Question 25

What happens on cloudy days?

Accepted Answer

The system is reduced in its electricity generation although this continues to generate energy since the system works with direct sunlight and although the clouds reduce it, they do not block it completely.
 
In the same way you should not worry about this since we calculate the size of your system considering the annual weather conditions based on historical installation area with studies conducted by specialized agencies such as NASA among others.

Question 26

What happens when there is a power outage or a considerable increase in voltage in CFE?

Accepted Answer

This will depend on the type of equipment you have chosen since for regulation and protection reasons, your system when detecting increases or decreases outside the parameters considered normal automatically disconnects your system from the network, ensuring the integrity of your equipment as well as that of the network and there is no energy exchange. So if your system has battery backup at that time it will come into operation and you will start to have only internal energy exchange and if your system does not have this backup then you will notice a cut in the power supply of the equipment and you will depend only on what the network will deliver you, and it may even be a total power outage.
The cut between the solar equipment and the grid is due to the fact that having a fault in the grid it could have compromised some wiring or equipment, endangering people or other electrical equipment and in turn requires a power cut for its repair necessary to ensure the integrity of the work team.

Question 27

Can I install my system?

Accepted Answer

It is not recommended since specialized technical knowledge is required as well as the legal registration of the system.
 
We deliver you a 100% installed and tested installed system.
 
We also include the legal procedures before the CFE and interconnection contract. The CFE will be in charge of changing the meter to be able to turn on the equipment and immediately start receiving the benefits.

Question 28

How long will the installation take with you?

Accepted Answer

This will depend on the size and complexity of the area but regularly a residential or commercial installation takes a day to be complete although for the powering up of the system it takes approximately 6 to 8 weeks due to administrative processes in CFE and the procedures that must be perform for registration, interconnection and finally the change of meter.

Question 29

What maintenance do I have to give and how much does it cost?

Accepted Answer

The maintenance of the equipment is basically to clean the dust or dirt of the panels with a rag and water without solvents or abrasives.
 
Inspection of connections and wiring sporadically is also recommended.

Question 30

Is the equipment dangerous?

Accepted Answer

No, although it produces high voltage, we take care of leaving everything well protected with special terminals that perfectly isolate the connections, however, its installation is recommended where children do not have access so that they do not introduce conductive materials into the various components or connections.

Question 31

Is there any government incentive for the purchase of these equipment?

Accepted Answer

Yes, according to article 34 section XIII of the ISR Law that says:
Deduction to "100% for machinery and equipment for the generation of energy from renewable sources or efficient electricity cogeneration systems".
This means that for Moral and Physical Persons with a tax obligation of ISR, within the first fiscal year (first year) they obtain an additional recovery that can be up to 38% of the total cost of the system, this will be according to your declared amount of profits and the tax tab.
If the payment is made with bank financing, the deduction will be applied according to the payments made each year within the contracted term.

Question 32

What is your coverage area?

Accepted Answer

We mainly carry out projects in western Mexico, including the Guadalajara metropolitan area, nearby towns, and the coasts of Jalisco, Colima, and Michoacán.

For other parts of the country, we assess each project individually to provide our clients with practical and cost-effective solutions.
