How long will the system take to pay itself back?

The payback period for a solar panel system can vary based on several factors. Factors such as energy usage, roof space, and usage behavior will impact the overall return on investment. Generally, a 4kW system is popular as a starting point, making a noticeable reduction in bills and grid reliance.

How many solar panels do I need?

The number of solar panels required depends on individual circumstances. Variables such as energy consumption, roof space, and usage behavior will influence the ideal quantity. A commonly chosen size is a 4kW system, a versatile option for various applications.

Now the feed-in tariff has ended, is there any point in solar?

Despite the end of feed-in tariffs, solar panels remain a valuable investment. They contribute to energy savings and environmental sustainability, making them a worthwhile consideration even without financial incentives.

Do I Need To Tell My DNO About My Solar Panels?

Yes, informing your Distribution Network Operator (DNO) about your solar panels is crucial. This ensures compliance with regulations and helps manage the impact on the grid.

What Does Kwp Mean?

Kwp stands for kilowatt-peak, a unit indicating the maximum power output a solar panel system can generate under optimal conditions.

Why do we oversize panel array to inverter output?

Oversizing the panel array to inverter output helps maximize energy production, especially during less than ideal conditions. This ensures efficient use of the inverter’s capacity.

Can I have a battery without solar panels?

Yes, it is possible to have a battery without solar panels. This allows you to store electricity during off-peak times or when rates are lower for later use.

Is a solar system a worthwhile investment?

Yes, a solar system is considered a worthwhile investment due to long-term cost savings, reduced environmental impact, and potential energy independence.

How long until my solar system has paid for itself?

The payback period varies but is generally influenced by factors like energy usage and local incentives. On average, many systems pay for themselves within 5 to 10 years.

What is a String inverter?

A String inverter is a type of inverter that manages the output of multiple solar panels connected in a series or “string.” It converts the direct current (DC) generated by the panels into alternating current (AC) for use in homes.

AC Coupled

AC coupling refers to a system where a battery is connected to the AC side of the inverter, allowing for greater flexibility and compatibility with different types of solar inverters.

What does kWh mean?

kWh stands for kilowatt-hour, a unit of energy measurement representing the amount of electricity consumed or generated over one hour.

Do solar panels only work on south-facing roofs?

While south-facing roofs generally receive more sunlight, solar panels can still be effective on east or west-facing roofs, with some reduction in efficiency.

Do I need a battery with my solar panel system?

While not mandatory, a battery enhances the benefits of a solar panel system by storing excess energy for later use, providing backup during power outages.

Do all solar systems export to the grid?

Not necessarily. Some solar systems are designed to be self-consumption oriented, meaning excess energy is used to charge batteries rather than being exported to the grid.

How long do solar panels last?

Solar panels have a lifespan of 25 to 30 years on average, and many manufacturers offer warranties for this duration.

What is a Hybrid inverter?

A Hybrid inverter is a versatile device that can manage both solar panels and energy storage (battery). It allows for greater control over energy usage and storage within a single system.
