Photovoltaic Technologies

Photovoltaic Solar Panels are distinct from other forms of solar energy in that it harnesses the light produced by the sun rather than its heat. This allows the panel to continue to produce electricity even when the sky is overcast.  Photovoltaic energy generation is the direct conversion of light into electricity. This is done by the use of solar cells.

The solar cells are formed from several thin layers of silicon. As light falls on these layers, electrons rush from one side of the silicon to the other creating an electrical current. The greater the number of cells the greater the current produced.  A number of solar cells connected together, is called a solar module. Multiple modules wired together form a Photovoltaic array.  As the electricity produced is DC (Direct Current) inverters are required to convert it to grid compliant AC (Alternating Current) which is the form we use in our homes every day.

 

When a system is designed, the panels must physically match the roof; the panel output must be carefully matched to a suitable inverter; the local solar irradiation and any shading must be taken into account; a mounting system must be designed to allow the panels to be safely and securely mounted on the roof; the wiring system must be designed so that the right voltage is fed to the inverter.

INVESTING IN SOLAR PV

Solar technologies can provide a cost-effective means of controlling your electricity bill, especially if utility rates continue to rise as the case is in Puerto Rico. Installing solar technologies can reduce or eliminate your exposure to rising electricity rates. Government incentives combined with decreases in solar equipment prices can make the investment in solar a good investment decision for homeowners, businesses and public agencies.

Every dollar, ($), spend on the system will be producing energy, which translates to depositing money onto a savings account, after the PV system has reached its amortization point.  This is environmental-friendly money that will continue to generate residual income throughout the lifetime of the system and it has been proven that PV Systems have an expected lifetime of 20+ years.  Therefore, is a win-win situation!
