Grid-Connected Solar Power System for Your Home

A grid-connected solar power system helps reduce the amount of electricity you purchase from the grid and lowers your electricity costs. If you have an electricity sales agreement, surplus electricity generated during the day can be sold back to the grid. Actual savings and revenue from electricity sales depend on your consumption profile, system size, electricity prices and the price paid for electricity exported to the grid.

Benefits of a Grid-Connected System

  • A solar power system covers part of your household electricity consumption with energy generated on site, reducing the amount of electricity purchased from the grid and the associated variable costs. Actual savings depend on your consumption profile, system size, electricity prices and the price paid for electricity exported to the grid.

  • Using solar energy helps reduce your home's carbon footprint and the need for electricity generated from fossil fuels. Electricity produced on site reduces the amount of energy purchased from the grid and supports the wider use of renewable energy.

    Altmer Energy complies with Estonia's producer responsibility requirements for electrical and electronic equipment placed on the market and arranges the collection and recycling of end-of-life equipment in cooperation with an authorised producer responsibility organisation.

  • A properly installed and documented solar power system can make a property more attractive and help reduce energy costs for a future owner. Its impact on the property's market value depends on the condition of the system, warranties, documentation and market conditions.

How Does It Work?

  • When there is insufficient sunlight (at night, during cloudy weather, or at times of increased demand), the system draws the missing electricity from the public grid. It is important to note that safety comes first: if voltage in the utility grid disappears, the inverter shuts down to prevent back-feeding into the lines. Therefore, a classic grid-tied solar power system does not operate during power outages.

    At the same time, such a system is extremely simple and efficient under normal conditions—the grid acts as a virtual battery, accepting excess energy and supplying electricity whenever it is needed.

Who Is It Suitable For?

A grid-connected system is suitable for households with a stable electricity supply whose main goal is to reduce the amount of electricity purchased from the grid and sell surplus solar production back to the grid.This solution is particularly beneficial for homes with high daytime electricity consumption, for example due to a heat pump, air conditioning or electric vehicle charging. Because the system does not include battery storage, the initial investment is generally lower than for a hybrid system.The payback period depends on the system cost, electricity consumption, solar production, electricity prices and the price paid for electricity exported to the grid.

Solar Power System Maintenance

A solar power system may appear to be operating normally, but without regular inspections, problems with connections, the inverter, protective devices or mounting structures can go unnoticed. Maintenance helps keep the system safe and efficient and allows potential faults to be detected early.
Keep Your Solar Power System Performing at Its Best — Book Professional Maintenance Today.

We provide comprehensive diagnostics and maintenance for solar power systems. We inspect inverters, electrical connections, protective devices, mounting structures and the condition of the panels, and measure the system's key electrical parameters.
Regular maintenance helps maintain stable energy production, reduce the risk of failures and extend the service life of the system.
