Solar PV
Understanding Solar PV
To help you better understand your investment, here's a brief overview of how Solar PV systems work, along with key factors that influence their performance.
How Solar PV (Photovoltaic) Works
Solar panels capture daylight and convert it directly into DC power (Direct Current). This DC power is then fed into an inverter, which transforms it into AC power – the type of electricity your home appliances use. Any excess electricity not immediately used by your home can either be sent back to the national grid or, ideally, stored in a battery storage system (BSS or ESS).
Key Factors Influencing Your System's Performance
The efficiency and output of your Solar PV depend on several important factors:
- Roof Suitability: The orientation (e.g., south-facing is generally ideal) and pitch of your roof, as well as the available unshaded space, are crucial for optimal daylight exposure and panel placement. East and west orientations are also suitable for solar panel placement; it just means at certain times of the day, one side of the roof will have more daylight than the other.
- Panel Stringing: Solar panels are connected together in "strings" to build up the required amount of power to activate and efficiently run your inverter. The orientation of your roof areas (e.g., panels on a south-facing roof versus an east or west-facing roof) often dictates how these strings are designed and connected, sometimes requiring separate strings or inverter inputs to maximise energy capture throughout the day.
- Shading: Nearby trees, chimneys, or adjacent buildings can cast shadows on solar panels, reducing their output. Even partial shading on one panel in a series string can significantly reduce the output of the entire string, impacting overall energy generation. Our design considers these factors to minimise their impact. To counter the impact of shading or individual panel performance variations, we can install Tigo Optimisers. These devices work at a panel level to ensure that each solar panel produces its maximum possible energy.
- Your Energy Consumption: Understanding your household's current and future electricity usage patterns (e.g., when you use the most energy) helps us size the system correctly to maximise your self-consumption and savings.
- Battery Sizing: The right battery capacity depends directly on your daily energy usage, how much solar power you generate, and your goals for energy independence.
Benefits You Can Expect
Investing in Solar PV offers a wide range of advantages for both your finances and the environment.
- Lower Energy Bills: Generate your own free electricity and reduce your reliance on expensive grid power.
- Energy Independence: Protect yourself from rising energy costs and gain more control over your power.
