Interesting facts for solar energy
There are many reasons to go solar; but the most common reason is to reduce your carbon footprint and cut energy costs.
Solar energy produces no pollution, has no detrimental environmental effects, and is ecologically sound.
Installing solar systems should not be looked at as an expense but rather as an investment.
The average American pays off their solar purchase in seven to eight years and sees a Return on Investment of about 20 to 30 percent.
Several tax breaks and financial incentives exist that make solar energy more accessible to homeowners. As a result, solar is a significant cabin efficiency upgrade that also increases the value of your property.
A power generation system (with backups) is a crucial feature of off-grid homes. So how do you meet all your energy needs from the power of the sun? The most critical step is to size your off-grid solar system. Sizing will determine the kind of equipment you need and the installation costs. To do so, you can refer to your average monthly electricity bills, or you can calculate the power usage, in kilowatt-hours (kWh), of all your electrical household appliances.
How much solar power do I need?
How much sun do you get?
It’s essential to know how many peak sun hours you typically get in whatever geographic area you are living in to determine your system’s size. It’s recommended to use the month of December as a guide as it receives the least amount of sun hours and using that month will assure you will calculate more than what you need.
For instance, Maine receives an average of 4.51 sun hours throughout the year but gets an average of 1.89 winter sun hours. Consider an off-grid household in Maine with several electric appliances, including a coffee machine, a fridge, microwave, TV-LCD, washing machine, electric clothes dryer, water heater, water pump, and an electric oven.
Typically, such a household would consume about 18kWh per day on average; this depends on how long the appliances are kept running. This household would require a system that can produce at least 9.5kW per day. This is a generalized system size estimation. Other factors to consider would include peak load, shade, and available panel space. An off-grid 10kW solar kit would work well for this household.
How many solar panels will you need?
The next step is to determine the number of solar panels. Typical residential solar panels usually produce about 250W per panel. Forty of these can produce 10kW per day and require about 700 square feet of roof space. If you don’t have enough space, you might have to consider using panels with higher wattage. For example, 27 370W panels would produce the required 10kW and would utilize less space.
Batteries and Inverter
A battery backup is a vital component of the solar system. The battery must provide enough backup power for nights as well as stormy/snowy days. The choice of battery is subjective and determined by the number of days of energy independence you’d like. For a 10kW system, a 30kWh battery will provide three days of energy usage.
The other two considerations for an off-grid solar system are the choice of solar charge controller and inverter. Solar charge controllers optimize battery charging and prevent the charge from flowing out the battery to the solar panels when there is no sun. An inverter converts solar power from DC to AC, which powers equipment and appliances in the home.
With this in mind, there are several solar kits available in the market, for example, the Eco-Worthy Solar System
Eco Worthy sells smaller sizes as well if your looking for less power. The one we are talking about above has:
- 15kWh daily output depending on how much sun your get, means full charge 48V 400Ah battery bank.
- Combiner box offers safer protection, with 10A fuse for each string, anti-backflow diodes and lighting protection.
- For charging battery and a backup power, suitable for off grid cabins,sheds and remote areas,etc.
- Easy setting up, the kit supports charging for 48V lead acid, gel, li-ion, flooded battery bank
- 1 year warranty with lifetime technical support, freely reach out to ECO-WORTHY professional customer service team.
If you want to go solar and have the option to hook up to the grid, this may be the best option as you can earn money in some places by selling power back to the grid.
