Solar PV systems are power systems that convert sunlight into electricity by converting the Sun's radiation, in the form of light, into usable electricity. It comprises the solar array and the balance of system components through a process in which semiconducting materials generate voltage and current when exposed to light.

A solar battery can store power during the day, so it's available at night. Depending on its installation a solar battery system can also turn your system into an emergency backup during power outages. Overall, batteries are valuable should you want a backup power source, who don't have full-retail net metering, or who live somewhere with substantial battery rebates and incentives.

Radiant barriers are usually installed in attics primarily to reduce heat gain and reduce cooling costs. The barriers consist of a highly reflective material that reflects radiant heat and are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic. Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system.

An electric vehicle charging station is equipment that connects an electric vehicle (EV) to a source of electricity to recharge electric cars, neighborhood electric vehicles and plug-in hybrids. Some charging stations have advanced features such as Smart metering, cellular capability and network connectivity.

Insulation in your home provides resistance to heat flow and lowers your heating and cooling costs. Properly insulating your home not only reduces heating and cooling costs, but also improves comfort. Many older homes have less insulation than homes built today, but even adding insulation to a newer home can pay for itself within a few years.

Solar thermal systems is a technology designed to harness sunlight for heat. This heat is often used for heating water used in homes, businesses, swimming pools, and for heating the insides of buildings. The systems can be installed in any climate to reduce utility bills and are composed of three main parts: the solar collector, insulated piping, and a hot water storage tank.
