What can a 400 watt solar panel run?
Photovoltaic modules are some of the most popular means of generating alternative energy. This is natural because such equipment is efficient, environmentally friendly, and affordable. One 400 watt solar panel from the catalog can provide electricity to your phone, computer, LED TV, lamps, and lighting fixtures. By purchasing several of these modules, you can satisfy all household needs by equipping a personal power plant.
When applying for the selection of equipment or choosing a solar power plant, customers often ask the question: how to calculate the power and number of solar panels and batteries? How many watts to choose for a home solar power plant? In this article, we will try to deal with this issue and explain how to do this without going into many details.
Correctly selected characteristics and placement of PV modules primarily affect the efficiency of a home power plant. The first thing to focus on when choosing is the type of crystals.
Monocrystalline panels are very efficient, but they only work when the sun rays hit at right angles of 90°, which is suitable for equatorial latitudes. The second option for using this type of solar panel is to put them on rotary trackers that regulate the angle of inclination to the Sun. With insufficient or incorrect illumination, there is a high probability that the generated current will not be enough to turn on the inverter.
They are mainly used in industrial solar power plants, where maximum electricity generation in a limited area is important.
In-home power plants, polycrystalline modules are more common. They work perfectly at any inclination to the Sun and produce electricity even from reflected light. Such panels have a lower automatic start threshold.
Appliance Power and Electricity Consumption
Revolutionary technology and innovative approach enable manufacturers to create new, more cost-effective solar panels of next-generation.
What about electrical appliances and their power consumption, here are the main ones that can be run by a 400-watt solar panel:
- Led TV – 50 - 150 watt
- Refrigerator class A – 100-300 watt (only when the compressor is running)
- Electric kettle – 1500 watt
- Laptop – 20-50 watt
- Energy-saving lamp – 30 watt, LED lamp 3-9 watt
- Wall-mounted boiler (electronics + built-in pump) – 70-130 watt
- Router – 10-20 watt
- Air conditioner – 700-900 watt
- Microwave – 500-700 watt
- Washing machine – 600 - 900 watt
- Video recorder + 4 cameras – 30-50 watt
- Portable stereos, CD and DVD players, or handled video games.
All powers are indicated in the hour of operation of the device. Therefore, it should be borne in mind that most devices work for a short time; the kettle is heated for 5 minutes, and the refrigerator is turned on every 2-3 hours for an hour to maintain the temperature. The boiler pump also works as the temperature of the coolant is maintained. If necessary, you can also calculate other devices according to this principle.
Maintenance of solar panels consists of a visual inspection for physical damage and periodic washing, usually two times a year (if there is not a lot of dust). Dirt and mud on your solar panel can reduce its efficient performance.
By installing 400-watt solar panels and modules, the owner of the power plant gets an excellent opportunity of the independent provision of his/her home with free electricity, without dependence on the state power grid. This is especially beneficial in cases when your house is located far from settlements and common trunk lines.
The wide range of 400-watt solar panels offers an impressive selection, depending on wattage ratings, shapes, and sizes that directly impact performance. Find high-quality, efficient solar panels capable of delivering superior power in both commercial and residential environments. Discover the largest selection of solar panels on the market.
