Grid-tied solar systems store your solar panel's energy in the utility grid. This system is the most affordable to install and does not require batteries. The utility grid stores energy generated by the system, and it is sold back to it when the demand is not met. This system can also produce more electricity per hour than the home, making it ideal for peak-hour usage.
Grid-tied solar energy systems have many benefits
One of the greatest benefits of grid-tied solar systems is the fact that they can reduce your utility bills. These systems can save you up to $156 per monthly after the payoff period. Not only will you save money on your energy bills, you will also receive credits from the utility company for the energy that your system produces.
Grid-tied solar panels have another advantage. They don't need backup generators nor batteries. Additionally, they can be more flexible in their sizing, as they do not have to meet the entire energy needs of a home. They can be placed in a place that is able to support future electric vehicle use.
Costs
A solar tie in grid system can help you reduce your electricity bills. Most utilities offer credits for solar power used in your home. Consider the costs. Grid-tied solar systems can help you reduce your costs significantly. You can expect to lower your power bills and to have extra power during peak usage times.
The cost of a grid-tied solar system will depend on the state you live in. Arizona's average residential installation price is lower than that of the nation. Massachusetts has a higher average price.
Maintenance
There are many things to keep in mind when maintaining your sun tie in grid system. First, you should determine the proper temperature for the system. Solar panels can be damaged if they are exposed to extreme temperatures. Second, you should take note of sudden increases in your utility bills. These are signs the system is in trouble.
Third, be aware of the cost associated with batteries. Batteries can be expensive and need to be replaced frequently. Like solar cells, batteries make up a large part of off grid PV installations. Regular flushing and replacement of normal lead acid batteries is necessary. Sealable lead acid battery can be chosen. These are more durable and require less maintenance. However, sealed lead acid batteries are expensive to buy and replace.
Seasons
Seasons can affect how solar energy is transferred from solar panel to grid. The amount and quality of sunlight hitting panels will change depending on the season. Additionally, the weather can affect how much electricity is needed to heat and cool. Because summer is longer and the sun shines brighter, a grid-tied solar system will have higher import/export rates. In winter, the days are shorter and the sun is not as strong, so solar power is less effective. Grid-tied solar systems are able to save credits and export surplus power when required.
In order to calculate the output of a solar tie in grid, you need to know how many hours you used in the year prior. This average should take into account all seasons, such as summer, winter and autumn. This is important as different seasons produce different amounts. Depending on how much they use, most customers will consume more energy during certain times of year.
Return on investment
The return on investment of a solar tie in grid system can be quite high. It can go up to 10-30% per year. Forbes estimates that an investment portfolio will return seven to a half percent over the long-term. Solar power is also a good investment that will help you reduce your tax liabilities, save the environment and has zero impact on budget.
Many experts agree that a sunroof installation is a wise investment. The ROI is better than five-year CDs and can help homeowners save a lot of money. According to Reuters, solar installations are a smart investment in ninety-five percent of US states. A trade lawsuit involving two module producers is challenging the return-on-investment of a solar tie into grid system.
