Why Solar – Environmental Reasons
Reduce your impact on the environment
– Control your carbon offset
– Increase your community’s awareness of energy independence
Over 30 years, the benefits of a 5kW system are equivalent to:
– Planting 30 acres of trees OR not driving 237,000 miles!
– Removing 190,000 lbs CO2 (greenhouse gas) from the atmosphere!

Other ways to reduce energy use
Power Stripping– Phantom Loads= 10-15% of your energy bill.
Power strips in each room of your home. Turn off when leaving. Important rooms – kitchen, home office or entertainment room.
Passive Solar Advantage– Open blinds during the day to let in sunlight during colder months
help heat your home. Keep blinds closed during warmer months to reduce your AC use

Why Solar- Economic Reasons
• Take Control of Your Electric costs:
-Reduce or eliminate your electric bills by $700 to $1,200 per year.
MA amongst the highest in the nation.
-Protect yourself from rising utility rates.
• Adds Value to Your Home:

Solar can add $20,000 in home value for every $1,000 of yearly energy cost savings.
