300 watt solar panels

Solar Panel 300 Watts

Solar panel 300W will help you lower your electric bill and prevent global warming at the same time. This solar panel can easily be installed on almost any roof and does not require maintenance. 300 watts solar panel has the best performance metrics in its class.

Few advices then choosing the 300w solar panel

When choosing the solar panel 300W, first you should look at its photo elements. There are mainly two choices: mono- and polycrystalline cells. Although cells are same in quality will have different performance metrics. Polycrystalline panels will be cheaper, but monocrystalline modules will produce more energy. There are also 300w flexible solar panels available in the market. This type of PV module is also called thin-film. The biggest advantage of 300 watt flexible solar panels is their low price and ability to fit many types of solar projects.

Choose the type of your solar PV system

Before purchasing a 300W solar panel kit, you need to decide what kind of system you want.

Off-grid with battery banks

Many homeowners prefer to install off-grid solar systems to become completely energy independent. The thing is that off-grid solar systems aren’t connected to the electricity grid, so they will continue working even if the public power grid is not functioning. However, this is only achievable with the appropriate equipment and batteries.

Grid-tight with net metering

Grid-tie solar systems, also referred to as on-grid, utility-interactive, grid intertie or grid backfeeding, are popular with both homes and businesses. They are connected to the utility power grid, which is necessary to run the PV system. It allows you to export any excess solar power you generate to the electricity grid, receive credits and use them later to offset your energy bill.

Hybrid

Hybrid solar systems incorporate the best features of grid-tied and off-grid solar systems, hence the name. Despite the fact they are connected to the utility grid, they have extra battery storage as a backup.

Once you decide on the system, you can choose the right equipment: battery, charge controller, string inverter or micro-inverter, switches and disconnects, and, most importantly, solar panels.

How many 300-watt solar panels do you need?

A 300W solar panel has a 300 watt rated power output. However, the actual power output will depend on many factors, such as geographic location, shading, weather conditions, and the tilt of your panels.

To understand how many solar panels 300 W you need to install, you have to calculate the amount of electricity you want to consume a day. You also need to know the number of peak sun hours (PSH) in your area. PSH describes the intensity of sunlight in a specific area, defined as an hour of sunlight that reaches about 1,000 watts of power per square meter (around 10.5 feet). Consult the map below to learn how many PHS there are in your state.

For example, if you live in Arizona and your daily energy consumption is 9 kW, you will want your 300 watt solar panel kit to generate 9,000 ÷ 6.3 ≈ 1,500 kW. It means that you’ll need 5 panels 300W to cover your energy needs.

Advantages of 300watt solar panels

• Photo cells are protected with tempered glass and encased in an aluminum frame. This protects the panel from elements and makes the panel secure to mount.
• Efficiency of 19% will let you harvest energy even in low light conditions.
• Solar modules normally come with 25 year warranty
• Panels do not require maintenance or service

300 W solar panels are designed to work well under the most challenging environmental conditions. Their operational temperature is usually from -40 to +185°F. In addition, 300 watt PV modules are impact-resistant, meaning they are able to withstand 2400 Pa wind load, 5400 Pa snow load, and 25 mm hailstones. However, the following conditions are required to get the most out of your panels:

• clear, non-cloudy summer day;
• zero shading;
• the temperature of about 77°F.
