To determine how much energy a system will produce, we must determine the system’s specific energy yield and capacity.
The system’s energy yield and capacity are calculated based on several considerations:
In the above example, the solar system would offset nearly 50% of the building’s annual electricity use (300,000 kWh), leading to $25,000 of savings in the first year.
In addition, the 100 kW solar system would qualify for significant Tax Credits and continue to save on energy costs, while also lowering the strain on the local electric grid and supplying excess electricity to surrounding buildings!
Solar Systems are incredibly reliable, given that there are no moving parts and only a few system components.Solar Inverters
Solar inverters typically last up to 20 years. It is important to budget and plan for an inverter replacement during the life of the solar system. The general rule of thumb is replacement after 15 years, but this can vary depending on inverter make, model, and maintenance.
