How much is a solar system for a 2000 sq ft house?
As global environmental issues grow, more and more people are looking to use solar photovoltaic systems to power their homes. However, for someone with a house area of 2,000 square feet, how many solar panels do they need? Are there other costs to consider? Below we will answer these questions in detail.
1. Calculate electricity consumption
First of all, we need to understand that the number of solar panels required to provide enough energy for a home is different. Therefore, the specific price will also vary. Generally speaking, if you want to install solar panels on a 2,000 square foot house, you need to know the amount of electricity the house needs each year. Because if the electricity is overdrawn, traditional energy will often be used, which in turn will increase additional costs. So, you need to consider the electricity demand of the home, because this will determine the number and specifications of solar panels to ensure that your home always has sufficient electricity supply.
The specific electricity consumption calculation can be estimated by referring to the previous electricity bills. The detailed electricity consumption can be checked by looking up the power of household appliances. Multiply the power of all household appliances by their monthly usage time and then add them up to get the specific kWh of electricity consumed per month.
2. Select the solar panel specifications and determine the quantity according to the power consumption
Assume that a family needs to consume about 400-700kWh of electricity per month. Depending on the usage, if more electricity is needed, the number of solar panels will also increase accordingly.
Assume we use Jingsun 750W N-type Bifacial Double Glass Module, the size is 7.82ftx4.27ftx0.11/0.1ft (2384±2mmx1303±2mm×35/30mm), the area is 33.4ft². Then 2000/33.4=59 pieces can be installed on a 2000ft² roof.
Total 59*750W=44,250W, Jingsun 750W N-type Bifacial Double Glass The price of each Module is $0.1. The final total price is $4,425. (Inquiry now)
Of course, based on the monthly household power consumption of 500-1,000kWh, it is far from necessary to calculate so many modules, unless the excess power can be sold to the grid to increase additional income, then there is no need to consider the household power consumption.
Then let's calculate in detail the number of solar panels required based on the monthly power consumption:
Daily power consumption: 17kWh-34kWh
The average daily power output of each 750W module under ideal conditions: 750Wx8hx80%=4.8kWh
The number of panels required is: 4-8
A total of 3,000W-6,000W gives a price of: $300-600.
3. Other costs
Of course, in addition to the cost of solar panels, the cost of installing solar panels also needs to be considered.
In addition, additional costs such as battery energy storage systems and regulatory fees also need to be considered. Battery energy storage systems can be used as backup power to provide electricity to homes at night or in bad weather. Currently, a system like this costs about $5,000 with 30 kWh of storage capacity. Regulatory fees vary from state to state and city to city, so you need to be aware of the regulations.
To summarize, the number and cost of solar panels required for a house of about 2,000 square feet will vary depending on the amount of electricity a home requires and some other factors. In addition, there are some additional costs, but they should be paid back in cost recovery. Using a solar photovoltaic system can greatly reduce energy costs and has a smaller impact on the environment, which is worth recommending.
