WattBack energy from the sun

No, they don’t. Third-generation Huasun panels based on HJT technology come equipped with 3 built-in bypass diodes, which automatically disconnect only the shaded portion of the panel. As a result, even if part of the panel is shaded (e.g. by a chimney, antenna, or tree), the rest of the panel continues operating at full power. This eliminates the need for external optimizers, simplifies the system, reduces installation costs, and increases overall reliability. Unlike conventional panels where shading can reduce output from the entire panel, Huasun HJT solves this issue at the architectural level — inside the panel itself.

With our online calculator, you can easily calculate the cost and payback period of a solar system. The calculator calculates:

• Total system capacity: The optimal system size for your energy consumption.
• Expected annual output: How much energy the system will produce in a year.
• Payback period: The time it will take for the system to pay for itself through savings.
• Payback period (including subsidy): The payback period considering the government subsidy of up to €1500.
• Savings over 10 and 20 years: The total amount of money saved over 10 and 20 years of operation.
• Total cost: The full cost of the system, including equipment, installation, and documentation processing.

The process of roof measurement and offer preparation consists of several stages:

1. Site Inspection:
   
   • We visit your property and conduct a roof inspection.
   • A drone is used to capture images and assess shading sources (trees, neighboring buildings, etc.).
2. Data Analysis:
   
   • Based on the images and measurements, we create a project in the PV SYST software, considering:
     
     • The annual movement of the sun.
     • Precipitation levels.
     • Shading and other obstacles.
   • To calculate the system’s capacity, we use data from your electricity bills (usually from the past 12 months). If bills are unavailable, we account for the family size, house area, and household appliances.
3. Offer Preparation:
   
   • We develop a project with a visualization of the future solar power plant.
   • We calculate the cost, payback period, and savings.
   • A detailed offer is prepared with a description of all work stages.

Important:

• The entire process is free of charge! You will receive a ready project and calculations with no obligations.

• You want to maximize the use of solar energy by storing excess power in batteries for use at night or on cloudy days.
• You’re aiming for energy independence and want to reduce your reliance on the grid.

How does it work?

• During the day, solar panels charge the batteries, and any excess energy can be sold back to the grid.
• At night or during a power outage, your home is powered by the stored energy in the batteries.

Why is it more expensive?

A hybrid system includes batteries and a special inverter, which increases the overall cost. However, it solves the problem of power interruptions and provides complete energy independence.

The exact cost depends on the system’s capacity, type of equipment, and installation conditions. To find out the total price, payback period, and potential benefits, use our online calculator. It will do all the calculations for you and show how profitable switching to solar energy can be.

A solar power system is not just about saving money — it’s about independence from rising energy prices and an investment in your future.

It’s the best choice for stable solar energy generation in the Cyprus climate!

Learn more about the manufacturer: Huasun Solar.

We design solar power stations to generate more electricity than your home consumes, ensuring a stable positive balance between export (energy sent to the grid) and import (energy taken from the grid).

How does it work?

During the day, your solar power station fully covers your home’s energy needs, and any excess energy is sent to the grid and recorded to your account.

Over the billing period, a bidirectional meter sums up all the exported (sent to the grid) and imported (taken from the grid) energy.

If the export exceeds the import, the difference is accumulated in your balance and used in the following months.

Why is it beneficial?

• Minimal or zero electricity bills – a properly calculated system meets your energy needs.
• Energy is stored in the grid – surplus generation isn’t wasted but used later.
• Full protection from tariff increases – your energy costs are locked in for years.
• Compliance with EAC requirements – our systems are guaranteed to be approved and connected to Net-Metering.

We build solar power stations that work for you – generating more energy than you consume and providing you with maximum savings and independence!
