Are solar photovoltaic systems a good investment?

For sites with time-of-use (TOU) and/or demand rates, solar PV systems are to be designed to offset the greatest amount of electricity in higher cost-rate periods and achieve the greatest annual dollar savings. Feasibility evaluations to determine the potential size of solar photovoltaic systems have not been completed.

What are photovoltaic panels & how do they work?

They are designed for builders constructing single family homes with pitched roofs, which offer adequate access to the attic after construction. It is assumed that aluminum framed photovoltaic (PV) panels mounted on a “post” and rail mounting system, the most common in the industry today, will be installed by the homeowner.

Do I need to meter a photovoltaic system?

It is assumed that aluminum framed photovoltaic (PV) panels mounted on a “post” and rail mounting system, the most common in the industry today, will be installed by the homeowner. While metering the system is encouraged, the specification does not address system wiring elements for associated system sensors or monitoring equipment.

How do I evaluate a solar array site?

To assist in evaluating each home, EPA has developed an online Renewable Energy Ready Home Solar Site Assessment Tool (RERH SSAT), which compares the solar resource potential of a proposed array site to the optimal solar resource potential at the same location.

Can a solar array be installed on a pitched roof?

If the proposed solar array location is on a surface that does not fall under the specification’s basic assumption of a single family home with a pitched roof that offers adequate attic access, EPA recommends that the builder consult with a certified solar energy professional when evaluating the home.
