What To Look For In An Unsecured Solar Loan

How Much Yield Can I Get From My Solar Power System ...

Unsecured loans with low rates and short repayment terms can help you pay off your solar panel system quickly. In contrast, you may be making smaller payments on a home equity line of credit for 10 or more years.

Annual percentage rate: The APR is the total cost of your loan, including interest and fees. Rates on personal loans range from about 6% to 36%, with the lowest rates reserved for good- and excellent-credit borrowers with little other debt. The APR can help you make an apples-to-apples comparison between personal loans and other financing options.

Fees: Some lenders charge an origination fee, which can be 1% to 6% of the cost of the loan, and is usually taken off the amount youre given.

Term: The amount of time you have to repay your loan helps to determine your monthly payments. With longer repayment terms, you have lower payments but youll pay more total interest.

Use a solar loan calculator to see how the loan’s rate and term affect monthly payments and overall interest.

The Final Calculation Of The Size Of The Solar Power System Needed

Once the daily power requirement estimation has been done, we need to check those calculations for each season. For instance, say the figure applicable to daily power requirement we arrived at is 240w.

We divide the daily watts required by the number of sunshine hours for the season to get the panel size .

  • 240 watt-hours/ 6 h = 40 Watt panel.

Similarly the calculation for winter daylight hours gives:

  • 240watt-hours / 4h= 60 Watt panel.

Depending on the brand of solar panel that you choose to buy, you will know the size of the solar panel you need. So if your chosen company makes 30 watt panels, then you need two panels connected in series. Note that based on the above calculations, the most satisfactory requirement for all year would be to use the higher number of watts and thus solar panels.

The above factors and metrics will help you in calculating the energy requirements for the solar power system that needs to be set up. There may be a difference in the estimated numbers from the actual watts output delivered. When the system is up and functioning you can adjust it.

How Much Do Solar Panels Cost To Install

To begin with, let’s take a look at the basic price range for solar panel installation. According to the most recent U.S. Solar Market InsightTM report, in the first quarter of 2021, the national average price of a residential solar system was $2.94 per watt, which would mean a 5 kWh system would cost $14,700 and a 10 kWh system would cost $29,400.

The exact price you’ll pay for solar panels will depend on a number of factors, including your geographic location, the size of your home and more.

Now, you might rightly wonder: What exactly are you paying for? The solar panels themselves usually make up just about a quarter of the total cost. Remaining expenses include labor, maintenance and additional parts and components .

Solar Panel Price Vs Return On Investment

Upfront costs for solar panel installation can be a little steep, which may leave you wondering how much money you will actually save and whether your energy savings will be enough to offset your initial investment.

It is not unreasonable to think that you can cut your monthly utility bills by as much as 75% or more by switching to solar energy. Of course, the specific dollar amount will depend on where you live, the size of your home and the number of people in your household.

One way to look at it: The average household energy bill is somewhere between $100 and $200 monthly. Based on these rates, it may take about 10 years for your energy savings to cancel out the cost of solar panel installation. However, factor in savings from tax rebates and other incentives, and most solar systems pay for themselves in closer to seven or eight years.

How Much Land Is Needed To Power The Us With Solar

The Biden administration has set a goal of reaching 100% clean electricity throughout the U.S. by 2035, and solar power is a key for this American energy transition.

In the last decade alone, solar has experienced an average annual growth rate of 42% in the U.S. thanks to federal tax credits, declining costs, and increasing demand. It is projected that more than one in seven American homes will have a solar power system by 2030.

To put this trend into perspective, this graphic uses data from the United States Department of Energy to see how much land would be needed to power the entire country with solar panels.

How Many Solar Panels Do I Need

Your energy needs determine how many panels you need, which affects the overall price of your solar system installation. To eliminate your electric bill entirely, you must generate 100% of the electricity your home needs. Most homeowners need between 25 and 35 panels to achieve complete energy independence.

Average households need867 kWh/monthin electrical power

A solar panel typically produces about one kilowatt-hour per day, so if your daily kWh usage is 30, you would need 30 solar panels to generate all of your energy needs. If you need to generate extra energy to heat a pool or run the air conditioning for most of the year, this adds to your energy costs.

To estimate the amount of energy youll need, you need to know your average kilowatt-hours . This number should be on your utility bill as kWh used. To get your monthly average, look at bills for the past year, add up the stated kWh used and divide by 12.

Next, divide your monthly kWh average by 30 to calculate your daily average. For instance, if your average monthly kWh is 900, then your average daily kWh is 30.

For a more accurate calculation, try to factor in times when there is not as much solar power available, like when its cloudy or in the evening. There are two main ways to account for this:

These additional calculations can be difficult, but they are necessary if you want the optimum solar power system for your home.

The Cost Of Installing Solar Panels For A Business

The average size of a commercial solar system is between a 50 kW and 100 kW. Solar systems of this size will typically cost between $100,000 and $250,000 before incentives are utilized. With the available incentives, solar owners could receive 26% to 75% of the systems cost back within the first year after installation.

The average agricultural and commercial solar owner can expect to save $100,000 to $350,000 over the 30+years of the solar systems life.

Without solar, the average business and farmer will spend $150,000 to $500,000 in electricity over 30 years.

Solar Panel Cost Per Square Foot

It is possible to use your home size to estimate the average cost of how much your solar panels will cost. Keep in mind that household energy needs vary a lot, regardless of the size. If you use many high-powered appliances, your energy needs could be higher even if your house is smaller.

In addition, the placement of the panels, which direction they face, and how much sun they receive also play a big role in your costs. The panel type and how many watts they produce also factor in. For this reason, you can have an enormous range of costs for this project, regardless of the home size.

As such, home size should only be used as a very general indicator of cost. A better way is to look at your region and your electric bill to determine how many watts you use each month. Then, you can determine how much you want to lower that by. The more you reduce your dependency on the grid, the higher the cost of your initial installation.

Solar Power For The Home: Costs

Solar power is capital intensive, and the main cost of owning a system comes upfront when buying the equipment. The solar module will almost certainly represent the largest single component of the overall expense.

Other equipment necessary for installation includes an inverter , metering equipment , and various housing components along with cables and wiring gear.

Some homeowners also consider battery storage. Historically, batteries have been prohibitively expensive and unnecessary if the utility pays for excess electricity that is fed into the grid . The installation labor cost must also be factored in.

In addition to installation costs, there are some further costs associated with operating and maintaining a PV solar array. Aside from cleaning the panels regularly, inverters and batteries generally need replacement after several years of use.

While the above costs are relatively straightforwardoften a solar installation company can quote a price for these for a homeownerdetermining subsidies available from the government and/or your local utility can prove more of a challenge. Government incentives change often, but historically, the U.S. government has allowed a tax credit of up to 30% of the system’s cost.
