Frequently Asked Questions

How do I know how much energy my house consumes?

Category:
Energy

There are two ways to obtain this information. The first would be to review the electricity bill you receive monthly. There you can get an idea of how much your consumption is in kilowatts. The second option would be to hire an electrician to come to your home and carry out a load census.

How many hours can the battery supply power?

Category:
Energy

That will depend on your use and the amount of battery storage, as well as your technology. To give an example: a 12 volt, 250 amp battery contains 3,000 watts. That means you have 3,000 watts to be able to consume up to what the battery specifications allow (it is not recommended to use batteries at their maximum capacity).

How do I know what type of system I need?

Category:
Usability

This is different for each person, as you must determine what you want a solar system for. Do you want it to power your entire home or run certain appliances in case of an emergency or power outage? Based on that answer, the type of system you need will be determined.

Can I continue adding panels to my system?

Category:
Usability

This will depend on the technical specifications of your inverter and batteries since each system has its limitations. All solar panel installations must comply with limits on connections, otherwise it may cause the system to explode or burn out. Also taking into account physical limitations such as the dimensions of the roof and size of the solar panels, among many other things.

How many discharge cycles does the battery have? What type of battery is it?

Category:
Usability

The one we currently have contains 1,200 discharge cycles. It is an AGM battery, which means it requires no maintenance.

What is the best type of solar panels?

Category:
Recommendations

There are many brands, models and types of solar panels. Generally speaking, monocrystalline and class A panels are the best solar panels. Additionally, having a bifacial panel captures a greater amount of light.

Are used solar panels worth it?

Category:
Recommendations

If they are in good condition, yes, since solar panels can produce energy for more than 25 years. Which means that a panel with a few years of use would still work well.

What are mono and poly panels?

Category:
Features

Monocrystalline panels are panels whose cells are made up of a single crystal and not many fragments as is the case of the polycrystalline panel. Many people debate which ones are better.
