A rooftop solar system uses solar panels to convert sunlight into electricity. The generated electricity is converted into usable power for your property through an inverter. Depending on the system design, energy can be used immediately, stored in batteries or supplied to the grid according to applicable regulations.
Rooftop systems are commonly designed as on-grid, off-grid or hybrid solutions. An on-grid system works with the electricity grid, an off-grid system can operate independently with suitable battery storage, and a hybrid system combines grid connectivity with battery backup.
System capacity depends on factors such as your electricity consumption, monthly bill, available roof area, sunlight conditions and the type of electrical loads you use. A site assessment and energy review can help determine an appropriate system size.
Before installation, the roof condition, available installation area, electrical requirements, shading and expected energy usage should be assessed. It is also important to understand the proposed equipment, installation scope, maintenance requirements and applicable local procedures.
The suitable panel technology depends on available roof space, energy requirements, project budget and site conditions. A solar professional can evaluate the property and recommend a panel configuration that matches the expected electricity generation requirement.
The process generally includes consultation, site assessment, system design, equipment selection, installation, electrical connection, testing and commissioning. The exact steps and timelines can vary depending on the property, system type and applicable approvals.
Solar projects may require documents related to the property, electricity connection and system installation. Requirements can vary by location, utility and project type, so the applicable authority or installation team should be consulted for the current process.
A solar inverter converts the electricity generated by solar panels into a form that can be used by electrical appliances. It also plays an important role in system monitoring and overall energy management, depending on the inverter technology selected.
