Home Solar Systems – Complete Solution for Energy Independence

Core components of a solar system

A complete solar system consists of photovoltaic panels (converting sunlight to electricity), an inverter (converting DC to AC power), batteries for storing excess energy, and a charge controller. The quality of each component directly affects the efficiency and lifespan of the entire system, so it's crucial to select mutually compatible parts.

Monocrystalline vs polycrystalline panels

Monocrystalline panels offer higher efficiency (18-22%) and require less space, making them ideal for smaller roofs. Polycrystalline panels are more affordable but have lower efficiency (15-17%), requiring larger surface area for the same output. For most households, monocrystalline panels justify the investment through superior long-term production.

Inverter types and their role

String inverters are the most common and affordable, but the entire system performs at the speed of the slowest panel. Micro-inverters are installed on each panel individually and maximize production even when part of the system is shaded. Hybrid inverters enable energy storage in batteries for nighttime use or backup power.

How to determine required system capacity

Analyze your average monthly consumption in kWh (visible on your electricity bill) and divide by 30 to get daily requirements. A 3-5 kW system covers the needs of an average household, while larger homes with electric heating may require 7-10 kW. Account for future consumption growth if you're planning to purchase an electric vehicle or heat pump.

Energy storage batteries

Lithium-ion batteries like those in AJAX systems offer long lifespan (10-15 years) and high efficiency (95%), but cost more upfront. Lead-acid batteries are cheaper but require regular maintenance and replacement every 3-5 years. Battery capacity should cover your nighttime consumption – the average household uses 5-10 kWh overnight.

What to check before purchasing

Verify that the manufacturer offers at least 10-year warranty on panels and 5 years on the inverter. Brands like Dahua and Eldes are known for reliable components with long operational life. Look for quality certifications (IEC 61215, IEC 61730) and check if the system is suitable for your region's climate conditions – some panels perform better in high temperatures.

Installation and permits

Professional installation is mandatory for warranty coverage and safety – improperly installed systems can damage your roof or cause fires. In Serbia, you need approval from the distribution operator for grid connection and registration of the system as an electricity producer. The platform allows you to compare prices of complete systems with and without installation, making budget planning easier.
