It’s a good idea to keep all of this in mind when you’re using the on-grid solar calculator. There are also federal tax credits for installing renewable energy sources, such as solar panels. However, there is no additional charge for storing your extra energy, and most states offer rebates and incentives through buyback programs. According to the National Renewable Energy Laboratory (NREL), battery-coupled systems can cost about twice as much as standalone systems. If a primary factor of your solar energy system is to store energy for later use, you will also need to invest in the proper number of batteries. As part of a grid-tie solar system, you’ll also have to decide whether you plan to use your renewable energy as a backup during an outage. Your energy consumption would remain the same as it was previously and the solar energy system would simply complement the setup that your home already had on the grid.īy using the on-grid solar calculator, you can figure out which solar panel kits will make the most sense based on the percentage of solar energy you intend to use. With this setup, your main objective might be to cut costs on your monthly electricity bill. You can also contact your utility company for more information that will help you to utilize the solar cost calculator.Ī grid-tie solar system means that your home is connected to the utility company’s grid. If your monthly electricity bill shows that your home used 800 kWh, that would be 800,000 watt-hours for the month or around 27,000 watt-hours per day (27 kilowatt-hours). To determine your watt-hours, simply take your kWh and multiply by 1000. Keep in mind that your bill shows your usage in kilowatt-hours (kWh), not watt-hours. If you’d rather not go around your house to determine each appliance’s wattage and daily usage, you can also reference your monthly electricity bill. For example, if you have a television that is 100 watts and you use it three hours per day, that would equal 300 watts per day. The most accurate way to use a solar cost calculator to calculate the total watts (W) that the electronics in your home will consume is to make a list of appliances you have and record their daily watt usage.
