Residential Solar Panels

Residential Solar Power System Installations

Solar photovoltaic (PV) panels on the roofs of homes and businesses use energy from the sun to generate electricity cleanly and quietly. The conversion of sunlight into electricity takes place in cells of specially fabricated semiconductor crystals.

Solar PV generates electricity only during the day, when there is sunlight, and generates electricity when it is needed most – during the day and during hot sunny periods when the demand for power (driven by air conditioners) is at its peak. Another advantage of residentlal solar PV is that it generates electricity at the point of demand (i.e. where people live and or work). Australia is one of the sunniest continents in the world. Given a stable policy environment, there is big potential for solar to make a significant contribution to electricity generation in Australia over the coming decades.

Australia has the highest uptake of solar globally, with around 30% of homes with rooftop solar PV. We have more than 3 million rooftop solar PV systems have been installed across Australia. Solar PV systems produces zero greenhouse gas emissions. Excess electricity can be directed into the grid (delivering a feed-in payment), or it can be stored in a rechargeable battery for later use. Batteries can also provide back-up power in the event of blackouts. Solar generation

In 2020, small-scale solar (systems up to 100 kW) was responsible for 23.5 per cent of Australia’s clean energy generation and produced 6.5 per cent of the country’s total electricity.

A solar PV system is a major investment. The market and technology are rapidly evolving. Offers, rebates and feed in tariffs differ among the states and territories, and are subject to change from time to time. A range of components and options need to be considered. Find out if the system can be upgraded as technology improves, you may be able to add batteries or more panels over time.

Be aware that there are low-quality solar panels around, as well as ‘deals’ that may not be what they seem. Crystal Solar Energy offers very reputed panels tested and endorsed by PVEL, a British Laboratory

A survey of 1000 solar owners and found that 33% had experienced problems with their system. Overall, 11% reported that their system was producing less energy than the installer told them it would and 21% had no idea if it was performing properly or not! At Crystal Solar Energy, we do monitor your pv system on a regular basis to ensure they are working well. We also educate you how to monitor the system in the monitoring portal.

Small scale PV systems are entitled to claim the STC for the installation. When a solar system is installed, a calculation can be done to confirm how many STC’s will be created over the life of your solar system, which is effectively a measure of the renewable energy generation from your system. Solar system installation companies typically offer an up-front discount equal to the value they can get when they sell the STC’s. This means these STCs for your system are being handed over by you to the solar system installation company in lieu of some of the payment for the system. Hence your upfront cost of solar pv installation is reduced.

The Feed In Tariff is set by the Essential Services Commission of Victoria. The minimum FIT is set at 6.7 cents/ kWh exported.
