# How Many Solar Panels Does Your House Need?

## Learn the basic formula for computing the number of solar panels for your home here.

Planning to power your home with solar energy? Congratulations and thank you for making the conscious decision to power your home with clean energy! For most homeowners, the obvious question that will come to mind is how many solar panels their home can accommodate. Is there a need to make room for more?

But did you know that the number of solar panels you need for your home solar power system relies on several factors? The easiest way is to consult a professional solar installer to get an estimated number of panels, together with the estimated cost. However, it is important that you have at least basic knowledge about solar panels!

Read on to learn the basic formula to compute the number of solar panels you need for your home.

## 1. How Much Solar Power You Need

You need to determine how much solar power you need. Take your hourly energy requirement and multiply it by the number of peak sunlight hours, and then divide it to a solar panel's wattage. To get a better estimate, you need to divide the previous figure into both a low and high wattage solar panel.

Your estimated energy usage plays a huge factor in determining the number of solar panels you need. To determine this, grab your electricity bill and check out your average monthly usage, which is in kilowatt-hours (KWH).

At this point, you want to also know your daily and hourly usage. If your bill doesn't show that, divide the monthly figure by 30 or 365 days, then divide the resulting figure again by 24 hours for the hourly usage.

Typically, a small home located in a temperate climate uses 200KWH per month, while larger homes that use huge airconditioners use around 2,000KWH. According to recent data, an average US household uses around 900KWH, or 30KWH daily or 1.25KWH per hour.

Do note that you also need to consider your location and your monthly usage during months when you use up a lot of energy. This is because these two other considerations will also greatly affect how much solar power you will actually need, and if you need to install additional features in case your home is idle or if you need more than the usual during the seasonal months.

## 3. The Peak Sunlight Hours In Your Location

Solar panels work best when they are placed in direct sunlight. This way, they can harness massive amounts of solar energy for you to fully maximize your solar power system. If any of the solar panels are not getting sunlight, they cannot produce the solar energy you need to power your home. As such, it is important that you determine your peak sunlight hours, particularly at the moment when the sun is directly overhead the location you intend to install the solar panels at.

To determine this, check your home's average hourly energy usage, then multiply by 1,000 converts hourly usage into watts. Then, divide the figure by the number of daily peak sunlight hours, which you can get here. The result will be the amount of wattage your solar panels need to produce every hour. Using our average US household example, a home that uses 900KWH per month that gets five peak sunlight hours daily requires your solar panels to produce 6,250 solar watts every hour.

## 4. The Quality of Solar Panels

Not all solar panels are the same. The solar panel type, sturdiness, technology, efficiency (or how well the solar panels convert sunlight into solar power), and panel size makes all the difference to be able to get the solar wattage you need to power your home in confidence.

Photovoltaic (PV) solar panels range from 150 to 370 watts per panel. Gridless solar panels absorb more sunlight than conventional solar panels and do not suffer integrity issues such as delamination (peeling), cracking, or corrosion. These solar panels, therefore, are more resistant. A microinverter on each solar panel can optimize solar power conversion at the source, which means more energy-efficient than having one huge inverter mounted somewhere in the house.

## Maximize the Power of the Sun With SunPower Solar Panels

An important consideration to mind when seeking quality solar panels is their efficiency and the maker. This way, you can rest assured that you are putting your money to work on something that will give you maximum energy savings as intended.

SunPower understands the importance of quality solar panels in residential homes. As such, they have developed elegant and durable solar panels with Maxeon® solar cell technology to maximize solar energy harnesses and conversion efficiency. Compared to a conventional solar panel, SunPower solar panels produce 60 percent more energy over the first 25 years of use, guaranteed. Moreover, their sleek and engineered design eliminates 85 percent of the issues that cause conventional solar panels to falter.

SunPower solar panels come with the SunPower Equinox® system + SunVault™ Storage system, designed to ensure your solar panels are working at their most efficient, and you can take control of the solar power that powers your home.

The best of it all? The solar panel system comes with a 25-year Complete Confidence Warranty, the only kind in the solar industry which covers your solar power system, including removal of a defective part, installation of any new part, shipping, and efficiency decline.

## Keep In Mind

You need to have the right number of solar panels to ensure that you have just enough and more to efficiently power your home in confidence. The panel size may matter, but solar panels with the maximum harness and conversion efficiency are better than the actual number. As this is going to be a long-term investment, quality is key for you to be able to reap and enjoy the benefits.
