The Cost and Benefits of Solar in Castleton
We know that for lots of homeowners, the choice to invest in solar hinges on installation costs. Some key things that impact the cost and possible savings include:

- Your city: This influences how much sunlight your roof gets, which helps determine how many panels you need.

EcoWatch's Castleton, VT Solar Company Rankings FAQs
What is the top solar panel installer in Castleton?
The highest-rated local solar company in Castleton is Northeast Solar, with a rating of 5.00 stars.
What are the major advantages and disadvantages of switching to solar?
The main advantages of solar power are that it can lower or, for some, 100% eradicate your electricity bills, raise your home's value and lower your carbon footprint. The main disadvantages are that solar panels can be pricey to install, you may not save a lot if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.
How long does it take for solar to pay for itself?
Solar panels usually pay for themselves in about 8.2 years, but your solar payback period will depend on your utility costs. The higher your typical power bill, the faster your solar panel system will recoup your installation costs.
What are the different types of solar panels?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can't, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much efficiency you're looking for.
