Grid-tied solar systems store the energy generated by solar panels in the utility network. This system requires no batteries and is the most cost-effective to set up. The utility grid stores this system's electricity and sells it back whenever the demand is not met. This system is ideal for peak hour use, when it can generate more electricity that the home requires.
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 could save you up $156 per calendar 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.
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. You can install them in a location that will allow for future use of electric cars.
Costs
Installing a solar tie in grid system is one way to reduce your power bills. Credits can be offered by many utilities for solar power that is used at your home. It is important to weigh the costs. Grid-tied systems can dramatically reduce your expenses. 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-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 is above the average.
Maintenance
There are several factors that need to be taken into account when maintaining your solar tie in grid system. You must first determine the correct temperature for the system. Extreme temperature differences can lead to damage to the solar panels. You should also be aware of sudden rises in your utility bills. These are signs that your system is failing.
Third, consider the price of batteries. It is expensive to purchase batteries and must be maintained. Like solar cells, batteries make up a large part of off grid PV installations. Normal lead-acid batteries need periodic replacement and flushing. Or, you could choose sealed lead acids batteries. These batteries last longer and require less care. However, sealed lead acids batteries are more expensive to replace and purchase.
Seasons
The way that solar power is transmitted from solar panels onto the grid depends on the season. 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. A grid-tied system will have a higher import/export rate during summer as the days are longer, and the sun shines less. Solar power is less effective in winter because the days are shorter and sun is weaker. Homes with solar panels connected to the grid can still save money and export excess power to the utility.
To calculate the energy output of a solar tie-in grid system, you will need to know how many kWh were used in the last year. This average should take into account all seasons, such as summer, winter and autumn. This is important as different seasons produce different amounts. The load in their homes will determine how much energy they consume.
Return on investment
The return on investment for a solar tie in grid can be high. It can go up to 10-30% per year. Forbes claims that an investment portfolio will usually return between seven and a quarter percent over the long run. 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. Recent Reuters research found that solar panels are a great investment in nearly ninety percent states. In a trade suit involving two module makers, however, the return of investment for a solar tie-in grid system is being challenged.
