Before the advent of modern technology, the only way to convert sunlight into energy was to get a sunburn while sticking your finger in a light socket. Manipulate the sun's rays safely with today's Groupon: for $99, you get $1,000 toward the installation of a solar-powered water-heating system from RES Solar. This Groupon is valid for homes within 30 miles of Scituate.

A cost-effective alternative to gas and electric heating systems, solar hot-water systems from RES Solar help stabilize long-term energy costs and reduce a home's double-wide carbon footprint. Using a liquid collection system, solar water-heating systems transport heated liquid from roof-mounted panels to a water heater so it can warm the aqua pura located therein. RES will dispatch sun-harnessing handymen for a free evaluation and comprehensive analysis of the home's hot-water use and then complete precise measurements and a thorough site visit before designing a heating system tailored to your home's unique energy needs. Although costs vary based on the system's size, $9,000 is the average cost for a domestic hot-water system that will be used by a family of four to six people or two adults and one Sasquatch.

RES systems are designed to be used in conjunction with pre-existing hot-water heating systems, and RES will assist homeowners in the completion of the federal and state paperwork to help them secure up to $5,000 in available tax breaks and credits. The green-energy gurus at RES use only high-quality OG-100 and OG300 SRCC-certified products and are able to monitor systems after they become operational to calculate energy savings and mediate feuds with local ceiling fans.
