What is a grid tied solar system?

A grid tied solar system is simply a solar system that is connected into the CFE electrical grid. The electricity that your solar system creates gets used by the house but if the system is creating more electricity than the house is using the excess electricity gets fed back onto the CFE Grid.

Do I just need solar panels?

Solar panels capture the suns energy and convert the energy into electricity; but to make that electricity usable i your home it needs to be converted from DC to AC. This requires an inverter. A quality inverter is a key part of your solar system.

How long do panels last?

Most solar panels have a 25 year output guarantee. That means that the manufacturer guarantees that the panel will still be outputting 80% after 25 years.

Do the warranties apply in Mexico?

Yes! We source all of our products from master distributors here in Mexico which means that all of our products enjoy their full warranties.  Some solar suppliers buy their products in the US and ship them down hoping to get a higher profit margin but in doing so lose the manufacturers warranty.

Does CFE actually pay for extra electricity that I produce with my panels?

No. CFE will give a full credit for any KWh that is created by your system but they never pay for the credit that you build up.  This is better than the majority of utility providers in the USA as most only give a partial credit.

What if I dont use the credit that I build up?

The credit that you build up is good for 12 months. After 12 months your credit is lost. For this reason it is important to work with a solar company that will properly size your system. At Ectech Solar we closely analyze your past usage to size your system in a away that never creates excess credit that you wont use.

Will the electricity I create be reflected on my CFE bill?

When we install your system we create a contract with CFE. At this point they swap out your meter with a “Smart” meter. Your meter then starts to keep track of any electricity that you put back onto the grid. When you get your first bill after the install you will see a new field showing the credit that you accumulated in that billing period.

What is the ``DAC`` rate?

Many have heard of the “DAC” rate; it stands for “Domestica de Alto Consumo” or High Consumption Domestic rate. Many who have larger homes and swimming pools are in this CFE rate. When a person is put into that rate they lose all government subsidy and pay the highest rate for every KWh they consume. Once in the DAC rate it is quite difficult to get out. In this situation a solar system pays for itself very quickly.

Is it easy to install a solar system?

While many companies sell “DIY” solar systems it is not simple to install a system properly. There are many factors to take into consideration such as waterproofing, hurricane resistance, electrical standards and safety, shading, etc.

Does CFE check the system?

Yes; Your grid tied solar system does have to meet the CFE safety requirements. After the installation a CFE engineer will come out to inspect the installation. He will check that the system is properly wired, that safety requirements are met, and that it meets their standards.

We have seen a lot of badly installed systems here in Baja. We pride ourselves on doing the highest quality installations around. This means we strive to do not only the best looking installations possible but also the most technically correct installations.

Although we arent required to here in Mexico; our systems are installed and wired to meet North American “NEC” code. This means we spend the extra time and money on our installations to:

  1. Use properly sized wiring
  2. Run all wiring in electrical conduit
  3. Do all splicing and connections in waterproof junction boxes
  4. Properly ground each component of the system
  5. Wire in line circuit breakers to
