Grid-tied solar systems store energy from your solar panels and connect it to the grid. This system does not require batteries and is the cheapest to put in. The utility grid stores this system's electricity and sells it back whenever the demand is not met. This system can also be used to produce more electricity than what the home uses during peak hours.
Grid-tied solar energy systems have many benefits
One of the best benefits of grid-tied systems is the ability to reduce your utility bills. These systems can save as much as $156 per month 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.
Another advantage of grid-tied solar systems is that they do not require batteries or backup generators. Additionally, they can be more flexible in their sizing, as they do not have to meet the entire energy needs of a home. These allow them to be installed in an area that can accommodate electric vehicles.
Costs
A solar tie in grid system can help you reduce your electricity bills. Many utilities offer credits for solar energy used in your home. You may also want to consider the cost involved. Grid-tied solar panels can significantly reduce your cost. You can expect to save money on your power bill and have extra power to help you during peak usage periods.
The cost of a grid connected solar system will depend on which state you live. In Arizona, for example, the average cost for a residential installation is below the national average. In Massachusetts, the average price is above average.
Maintenance
Maintaining your solar tie in grid system requires consideration of many factors. First, establish the appropriate temperature. Solar panels can be damaged if they are exposed to extreme temperatures. A second indicator is an increase in your utility bills. These are signs the system is in trouble.
Third, be aware of the cost associated with batteries. Batteries are expensive to acquire and must be replaced periodically. Like solar cells, batteries make up a large part of off grid PV installations. Regular replacement and flushing of lead acid batteries are necessary. Alternatively, you can choose sealed lead acid batteries. These batteries are more long-lasting and require less maintenance. However, sealed batteries with lead acid are more costly to buy and to replace.
Seasons
The seasons affect how solar power is transferred from the panels to the grid. The amount that sunlight hits the panels will vary according to the season. Furthermore, the weather will have an impact on how much electricity is required for heating/cooling. Because summer is longer and the sun shines brighter, a grid-tied solar system will have higher import/export rates. Solar power is less effective in winter because the days are shorter and sun is weaker. Still, homes with grid-tied solar systems can save credits and export surplus power to the utility when needed.
For calculating the energy output of the solar tie in grid system you need to know the number of kWh that you used over the past year. This average should take into account all seasons, such as summer, winter and autumn. This is crucial because different seasons will produce different amounts. Most customers will use more energy at certain times of the year depending on the load inside their homes.
Return on investment
A solar tie-in grid system can provide a high return on investment. 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.
Experts agree that a solar system is a good investment. A solar installation can provide homeowners with a better ROI than five-year CDs. It can also help them save money. According to Reuters, solar installations are a smart investment in ninety-five percent of US states. The return on investment for solar tie in grid systems is being challenged by a trade lawsuit that involves two module manufacturers.
