Most solar panels have an expected lifetime of 25 years, with very little maintenance required. The individual components have lifetimes of ten years and up. The cost of maintenance and extended warranties will be an important factor of the project’s
Because photovoltaic (PV) solar systems use the full spectrum of light, the ultraviolet rays are still charging the system, even when the sunlight isn’t visible. Obviously, the system will produce more power on bright sunny days. In the event of
Solar systems that produce electricity are known as photovoltaic, or PV, systems. The term “photovoltaics” refers to the direct conversion of light into electricity at the atomic level, using silicon semiconductor materials. The power produced in direct current, or DC.
Any project built at the RTS has to be done in conjunction with the State Department of Environmental Protection (DEP), who is responsible for insuring that closed and capped landfills do not pose an environmental threat. The system can be
The PV panels, mounted in frames (arrays), would go on top of the capped former landfill. (This is the flat-topped “hill” that you see, behind the transfer station area.) The transfer station, yard waste and composting areas won’t be affected.
There are multiple options for developing a PV array, but they break out into two general categories: land lease, where the municipality leases land to a private solar developer who builds, owns and operates the facility. The municipality incurs little
Based on preliminary assessments, Green Needham believes that the area top of the capped landfill could support a 2-3 Megawatt (MW) Solar PV system. A 2 MW system would generate about 2.3 million kilowatt hours (kWh) of electricity per year,
