How Much Is Solar Panels In Hawaii

Formulas Used To Calculate Solar Power Needs

Tesla solar panels are starting to power Hawaii island

With these factors in mind, you can more easily figure out how much solar power your home is going to need to operate at normal levels.

To start, you should add up how much kWh usage your household has had over the past 12 months, and then divide that number by 12 to get the average.

The second thing to look at is how many hours of sunlight your home gets. The peak hours that are most important here are the hours that offer at least 1,000 watts of photovoltaic power per square meter. If you live in the US, your peak hours can range from about 3 to 7 hours.

The formula youll use is average kWh use / . As an example, your formula might look something like this:

812 kWh / = 4.92 kW solar system

Once you have the number for your needed kW, you have to convert it into the wattage output from a solar panel. 1 kW is the same as 1,000 watts, so you have to multiply by 1,000. With our example, that will look like this:

4.92 x 1,000 = 4,920

Next, we will divide that number by the output that an average solar panel has. If youre using standard panels with 250-watt output, youll use that information to figure out how many panels youll need in total. Using our example here, the formula will look like this:

4,920 / 250 = 19.68 solar panels

If you live somewhere that gets 5.5 hours of peak sun and use 812 kWh per month, youll need a 4.92 kW system with close to 19.68 solar panels to completely power your home.

Eliminating Your Electric Bill In Hawaii

In many cases, you can significantly reduce your reliance on the energy grid. Some homeowners have been able to experience significant savings over the lifetime of the unit.

Some solar systems, depending on energy output, can pay for themselves in about four years.

Whether you lease or buy the system, youll be able to benefit almost immediately from renewable energy.

How Much Are Solar Panels In Hawaii

The cost of solar panels in Hawaii depends on many factors, including the size of your home and system, where your home is located and how many watts of energy you will need. Currently, there are federal solar tax credits available that can help you save even more.

You dont have to buy solar panels to have them installed on your home! One of the most popular ways to go solar is the solar lease, where a solar company installs and owns the solar panels but gives you a permanently discounted electricity rate. These deals, while they wont save you as much as owning the panels in the long run, are nearly pain-free and save you money from day one.

How Much Energy Do You Use

In 2020, the average American household had about 10,715 kilowatt-hours in electricity usage.

You need to consider how many appliances you use that require electricity and how often they run to figure out your energy usage. Your electricity bill will likely tell you the kWh, which stands for kilowatt-hours, which is the direct measurement used for figuring out energy consumption.

A larger home might use more electricity overall simply because there is more stuff in it to power, so youll need more solar panels if you live in a bigger house. However, you might live in a larger house that uses a lot of energy-efficient appliances.

If you compare the electricity usage of a home with a lot of Energy Star appliances to a home with older appliances, this is going to make a big difference. Keep in mind that anything plugged in will use power, including things that you may forget about like the refrigerator or your clothes dryer.

The best way to figure out how much power youll need from residential solar panels is by looking at your electricity bills. You can see past bills and compare them to more recent bills to see how your energy needs may have changed over time.

How Many Solar Panels For 3000 Kwh A Month

The guideline above will work, but there are a lot of variables involved here. How much of the power do you want to run from solar? Are you on the grid or off it? Do you own a large house or a farm? Where do you live and how many sunlight hours do you receive?

You can ask a solar panel provider to conduct an assessment on your property, but you can do it yourself using the following information. You can then determine how many solar panels you will need.

The formula is average sun hours per day x 30 / kwh per month = solar panel size

If you need 3000 kwh per month and the property receives 5 hours of sunlight a day, that would be 5 x 30 = 150.

3000 / 150 = 20. You need at least 20 kwh, or better yet 21.5 kwh to offset energy losses.

If you want solar power to produce 80% of the power, multiply kwh per month by .8.

3000 x .8 = 2400. You need 2400W to convert 80% of your monthly energy usage into solar.

Whether you own a house or a farm, calculating how many solar panels you need is the same process. The numbers given here are examples, so you can substitute whatever numbers you require.

Not Sure What I Did Before Discovering This Product Its Super

Solar Help is a genuine class act!!! I contacted them to assist in a panel take down and reinstall for a roof replacement. The pricing is more than fair, communication for coordination was simple, and the panel team were so effecient that the take down and reset was as if they were never there. I left for work in the moring to return to panels neatly situated out of the way so the roofers can do their work. When it came time to reset, the same scenario, I returned home to a new roof with solar panels back in place and powering my home. I just wanted to say thank you and recognize the company for what it is… FIRST RATE CLASS ACT!!!

Should You Go 100% Solar Power On A 3000kwh System

If you want to go 100% solar, you must have a battery bank or access to solar buyback or net metering as your energy usage will vary season by season. Without any of these you could waste solar power production.

Suppose your house needs 3000 kwh during the summer and 3300 kwh during the winter. If your system generates 3200 kwh during the summer, the extra power goes to waste. On the other hand, production may drop to 2900 kwh during the winter, falling short of what you need.

Solar panel ratings and output differ, and when you add the changing weather you could end up with an overabundance or lack of solar power. There are two solutions, net metering and solar batteries.

Net Metering

Net metering or solar buyback is a program that allows you to sell excess solar energy to the power company in exchange for credit. If you produce an extra 200 kwh in July, you can sell it to the utility company. When your system production drops in November, you can use the extra credit and get electricity without paying a higher bill.

The benefit of net metering or solar buy back is no energy is wasted. Your solar system can produce more than 3000 kwh a month and you can use that as credit for later use.

Solar Batteries

If you do not have net metering, you can buy batteries for energy storage. Batteries will add to your cost, but with it your solar system can produce whatever amount and the extra gets stored. You can even go off grid with a large battery bank and an inverter
