Educating the community… even our competitors and old suppliers!

This week I came across some very hateful, bigot and racist opinions about our company, our website and some of our employees.

If these comments were from an actual customer, we would take them serious, but the ip address that originates such comments is from Florida and other out of state locations, and the signature is from a Concerned Brownsville Citizen. While we know exactly who made such comments, we are very happy that our competitors and old suppliers are following our blog. This means we at least are educating them in how to proceed in difficult situations and avoid making mistakes with their customers.

The solar industry is an industry that is trying to prove itself to its customers and the general public.

If you buy a television at any retailer, or a computer, or any electrical component, the standard guarantee is one year, which you can extend to 2 to 4 years by paying for additional coverage.

In the solar industry, the minimum guarantee is 5 years by law, and regularly a solar installer or integrator will provide 20 years in the solar panels and 10 years on the inverters.  It is wise to request both the warranties of the factory and the installer and to cover your investment in both ways.
In the past years we have had to back the following manufacturers that went out of business in the United States:




just to name a few.

If your installer is suggesting to use microinverters, ask them to give you a non-questions ask guarantee in the United States that is equivalent to a non-micro inverter.
As a general rule, all electric components work beter in cold environments, so I am very skeptic when someone suggest to put an inverter in the warmest enviroment in the property: The Roof.

There are many reviews that cover this topic, just google Micro Inverter Review and aim for the biggest companies with reputable reputation. As we always recommend, aim to American Made product.
