Solar panels are no longer just for hippies.
If you\'re equally interested in saving money and saving the planet, solar panels can help you do that.
Their prices have fallen, their effectiveness has increased, and Congress has extended the installation of their 30% federal tax credit to the end of 2019.
All of this means that solar panels can now pay for themselves in five years, depending on where you live.
But are they suitable for your home?
This question raises more questions.
Ask yourself these things before making a decision.
In which direction is your roof tilted?
Because of America\'s position on the Sun, South-
Roof-facing solar power generation is the most efficient, followed by the West
Facing and then eastfacing roofs. North-
Facing the roof is the least ideal for solar energy, and many have ruled out the possibility.
Is there a shadow on your roof?
Ideally, the sun hits your panel for at least five hours a day.
If trees, hills, or other buildings block the sun from reaching the roof, that\'s a problem. (
Remember: especially in this city, there may be a tall building next door in the future. )
How big is your roof?
It takes about 100 square feet per kilowatt of solar energy.
Average residential solar system is 5 KW20 panels —in size.
So, you need about 500 square feet of space.
What is the angle of your roof?
The ideal angle for solar panels is 30 degrees, but they can be mounted on a roof from zero to 45 degrees.
Solar panels on flat roofs are mounted on tilted racks.
The sun may not reach the distance if your roof is very steep.
Study your roof all day and see what\'s going on.
What kind of roof do you have?
Installing solar panels on asphalt wooden tiles or corrugated metal roofs is the easiest.
Placing them on a slate or tile roof is more complex and expensive.
Your jurisdiction may not allow solar panels to be installed on wood-shaken roofs, as this is a potential fire hazard.
How big is your roof?
The solar system usually lasts between 25 and 30 years.
This means that when you install solar panels, there should be many years left on your roof.
Otherwise, you have to delete them temporarily when you replace them, which increases the cost.
What size system do you need?
Please note that the salesperson may be too optimistic about how much power the solar system will generate.
That\'s why you should run these numbers using Doe\'s Fair PVWatts calculator.
Typical five
The kilowatt-hour system generates an average of 7,000 KW hours per year.
How long are you going to stay in this House?
If you are going to stay at home long enough to have solar panels pay for yourself, it would be best because it is difficult to predict how much potential buyers value solar panels, and if you can recover the cost.
How expensive is your electricity?
Solar panels are more valuable to you if you live in places with high electricity bills. The U. S.
The Energy Information Administration provides a map of electricity prices so you can see how your status is compared.
Confirm by looking at the hourly rate per kWh on the bill.
What are the national incentives?
Many states offer their own incentives on the basis of federal tax credits.
For example, Maryland will pay $1,000 for residents to install solar systems.
You can find your state in the renewable energy and efficiency national incentive database.
Do you have a net measurement in your state?
Net metering means that if you generate more than you need, the power company will buy back from you, which may be beneficial. Thirty-
Is my state the state of SREC?
About 30 states plus the region require power companies to generate electricity from renewable sources such as solar energy.
The power company will pay you to help them do this.
The SREC represents the solar renewable energy certificate.
Every time you generate 1,000 KW solar energy, you get a srecc.
Your utility company will buy it from you.
Up to $480 in some areas.
How is the weather in your state?
Apart from parts of Alaska, solar panels should work in most states.
However, you can check the average sun days in your state to see how efficient your system may be.
Should you buy solar panels?
Standard five-
The average cost of the KW system is about $16,000.
$11,000 after the federal tax credit.
If you can afford it, buying solar panels directly will give you the most return on investment.
If not, then you can get a solar loan.
The best option for those with strong funding is a secured solar loan, which means you can use your house as a mortgage.
The interest rate will be lower than the unsecured solar loan and the interest will be taxdeductible.
Should you rent the panel?
About half of the states have solar leases.
The company installs solar panels for you in exchange for your government rewards.
Like renting a car, you don\'t need to pay much in advance, but you have to pay the company\'s monthly rent for up to 20 years.
The problem is that when these years have passed, you have nothing left.
Either the company will remove the solar panels or you will have to buy them.
The PPA or the \"power purchase agreement\" is similar to a solar lease, except that you agree to pay for the electricity produced by the company\'s panels rather than paying the rent.
If the question seems to be more than the answer, then the bottom line is: if you have the right roof, your local electricity price is high, and your country offers a lot of incentives, now is the time to study solar energy seriously.
