The State of Massachusetts has set an ambitious goal to achieve 250 MW of solar power installations by 2017, and in support of that goal has established a number of incentive programs available to businesses and homeowners alike. The Commonwealth Solar II Rebate Program provides rebates based on the size and other characteristics of the project. Part of our project management for your installation includes assisting you in applying for such rebates.
The sun’s energy is collected through a number of technologies: passive solar and solar thermal to heat air and hot water, and photovoltaics to generate electricity.
Solar Thermal – Active solar thermal systems collect solar radiation to heat air and/or water for commercial, industrial or residential use. A pump in a solar hot water collector circulates the water which is warmed up and used to provide heat or hot water to the building. There are many types of solar water heaters on the market and RALCO will guide you to the most suitable selection for your building
Passive Solar – The absorption of sunlight through south-facing windows, using dark-colored, dense material refers to passive solar design. Passive solar design techniques are most easily applied when designing a new building to collect, store and distribute solar energy as heat.
Solar Voltaic – A solar photovoltaic module is an array of cells containing semiconductor materials that convert solar radiation into direct current electricity. Installations that include a solar PV system connected to the power grid will feed any excess electricity it produces into the grid and credited on your electricity account. Over the last 10 years, the installed cost of solar PV has dropped 30%. Contact RALCO to evaluate your options.
The Commonwealth’s goal is to install 2000 megawatts of wind energy by 2020 and to reach that goal, the State is providing a number of incentives for various size projects: community scale, microwind and commercial wind.
Consider these numbers: a single 1 MW turbine on land can provide enough electricity to power 225 to 300 households. A single 1 MW turbine in an offshore wind farm, where the wind blows harder and more consistently, can power more than 400 households.
Wind turbines are surprisingly quiet, considering they are large, rotating structures. Noise impacts are regulated by municipalities as well as the Massachusetts Department of Environmental Protection (MassDEP), and should not be a factor for wind projects.
Residential wind turbines
If you did not think about wind turbines as an alternative energy solution, think again. Roof-top wind turbines and pole-mounted turbines have come on the market and offer very quiet and safe options.
