A grid-tied solar system stores energy generated by your solar panels in the utility grid. This system is the least expensive to install upfront and does not require batteries. The system's energy is stored by the utility grid and is sold back to the company when the sun's rays do not meet the demand. 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
Grid-tied solar systems can help you reduce your utility bills. This is one of the biggest benefits. 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 systems are also more cost-effective than traditional backup generators and batteries. Grid-tied solar systems are also more flexible in sizing because they do not need to meet all of the energy needs of a residence. This allows them to be installed at a location that will be able to accommodate the future use of electric vehicles.
Costs
One way to lower your power bills is to install a solar tie-in grid system. You can get credits from your utility for using solar power in your home. It is important to weigh the costs. Grid-tied, solar systems can greatly reduce your monthly costs. 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' average price is higher than average.
Maintenance
You must consider several factors when maintaining your solar tiein grid system. First, determine the ideal temperature for the system. Temperature variations can cause damage to solar panels. A second thing to be aware of is sudden increases in your utility bill. These are indicators that something is wrong with the system.
The third thing you need to consider is the cost of your batteries. Batteries can be expensive and need to be replaced frequently. Batteries, unlike solar cells are a major component of off-grid PV installation. 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 batteries with lead acid are more costly to buy and to replace.
Seasons
The way that solar power is transmitted from solar panels onto the grid depends on the season. The amount of sunlight hitting the panels will vary depending on the season, and weather will also affect the amount of electricity needed for heating and cooling. Grid-tied solar systems have a greater import/export ratio because summer days are longer. Winter is shorter and the sun shines less so solar power is less efficient. Grid-tied solar systems are able to save credits and export surplus power when required.
You will need to know how much kWh you have used in the previous year in order to calculate the energy output from a grid system with solar tie-ins. This average should cover all seasons, including winter, summer, and fall. 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. This can be anywhere from 10-30 percent per annum. Forbes estimates that an investment portfolio will return seven to a half percent over the long-term. Furthermore, solar power investments will lower your tax liability, help the environment, and have no impact on your budget.
Many experts agree that a sunroof installation is a wise investment. A solar system can offer homeowners savings of up to 80% over five-year CDs. According to a Reuters survey, solar installations make good investments in nearly all states. Two module manufacturers are suing to challenge the return on investment of solar tie-in grid systems.
