A large majority of grid-tied solar PV systems are battery-less systems that utilize a net metering arrangement with the electric utilities to receive compensation for additional electricity that they deliver to the grid.
Insource Renewables provides full-service design and installation of solar grid-tied PV systems for residential and commercial clients in Maine.
Off-grid solar PV systems utilize solar batteries to store electricity when there is sufficient solar radiation to satisfy the electrical demands in the home. The solar plus storage systems, also known as “standalone” systems, range from small systems for running emergency signs and lighting to systems that satisfy the full energy demands of a home or business. These systems are typically utilized in places where access to the grid is impractical or expensive. These systems are commonly used for seasonal cabins and homes located away from existing electrical infrastructure.
We provide the design and installation of off-grid solar PV systems and generators. Typically, our off-grid clientele are those who are looking for whole-house systems or larger camp systems.
Like a refrigerator or air conditioner, heat pumps use refrigerant, a compressor, and various valves to move heat from one area to another. Mini-split heat pumps (MSHPs) move heat into a home or business during the heating season and provide cooling or dehumidification in the summer. The electricity required by these appliances to move heat costs significantly less than burning oil or propane.
Solar water heating technologies absorb the sun’s radiation for domestic water heating or commercial water heating. Well-designed and properly installed solar water heating systems last for decades and provide their owners with significant cost savings.
Solar water heating systems are cost effective solutions for homes and businesses with moderate to high water heating loads. In residential applications, these systems are designed to offset 60-70% of the energy required for annual water heating. With an auxiliary source of heat, such as oil, propane, or electricity, owners always have the comfort of hot water without the typical energy costs.
Solar pool heating (SPH) systems are the most popular solar heating system in the United States. SPH systems are very simple and provide a viable alternative to heating a swimming pool with gas, oil, or electricity. They have virtually no operating costs, which results in an almost immediate payback for pools that would otherwise be heated with fossil fuels or electricity.
A solar pool heating system is the most cost-effective heating solution for pool owners seeking greater comfort or looking to extend the swimming season. These systems use simple polypropylene collectors that can maintain temperatures of 85-90 degrees Fahrenheit through the typical swimming season.
Insource Renewables designs and installs solar pool heating systems for residential and commercial applications.
Our owner, Vaughan Woodruff, authored two articles for Home Power magazine related to swimming pool energy efficiency and solar pool heating. These articles provide insight into effective solutions for getting the most enjoyment out of your pool:
Electric vehicle (EV) charging stations provide electric car owners with convenience and faster recharging than is available with a standard 120V outlet. These units provide are especially useful to EV owners who use their car as a daily driver or to businesses that see benefit in providing EV charging to the public or to their customers.
We have a highly qualified staff of electricians ready to serve your EV charging needs. When combined with solar, this solution offers Mainers the option to power their transportation needs with the sun.
