Solar self-consumption

Solar self-consumption involves generating electricity from solar panels installed on residential properties and using it for household consumption. Excess energy generated by the solar system is fed back into the grid network, and credit is provided by the power suppliers.

Each supplier offers its own tariff for solar energy, with varying rates. These tariffs may be referred to by different terms such as Solar Wallet, virtual storage, virtual battery, or cloud storage. Some suppliers use the accumulated credit to offset the overall monthly invoice, resulting in many clients having €0 to pay each month, while others may only pay a nominal amount.

With the increasing availability and affordability of residential solar panels, coupled with rising electricity costs and environmental concerns, solar self-consumption has gained significant popularity.

Key benefits of solar self-consumption include substantial cost savings on electricity bills, enhanced energy independence, and a reduced carbon footprint. By harnessing sunlight to power homes, individuals can significantly lower their reliance on fossil fuels, contributing to a greener, more sustainable future.

How Solar Self-Consumption Works

A solar self-consumption system comprises several essential components, including solar panels, an inverter, and optionally, battery storage. Solar panels convert sunlight into electricity through photovoltaic cells, which are then converted from direct current (DC) to alternating current (AC) by the inverter for use in the household. Excess energy can either be stored in batteries for later use or exported to the grid, depending on system configuration and local regulations.

The process of generating and using solar electricity is straightforward: solar panels absorb sunlight during the day, converting it into electricity to power household appliances and devices. Any surplus energy is stored in batteries or exported to the grid. At night or during periods of low sunlight, electricity is drawn from the grid or battery storage to meet household demand.

Benefits of Solar Self-Consumption

The benefits of solar self-consumption are manifold. Firstly, homeowners can experience significant cost savings on their electricity bills by generating their own power. This is particularly advantageous in regions with plenty of sunlight and high electricity rates. Moreover, solar self-consumption reduces dependence on the grid, providing greater energy security and independence.

From an environmental standpoint, solar self-consumption contributes to a reduction in greenhouse gas emissions by displacing electricity generated from fossil fuels. Additionally, adopting solar energy can increase property value, offering a compelling return on investment for homeowners.

Government incentives for solar self-consumption vary by location but may include tax credits, rebates, and net metering programs. Interested individuals should research relevant incentives and subsidies available in their area to maximize savings.

Things to Consider Before Going Solar

Before investing in a solar self-consumption system, several factors should be taken into account. These include roof suitability, sun exposure, electricity usage patterns, and initial investment costs. Consulting with a professional solar installer can help assess these factors and determine the optimal system size and configuration.

Financing options for solar installations may include outright purchase, solar loans, or leasing arrangements. It’s essential to evaluate the long-term financial implications of each option and choose the most suitable financing method based on individual circumstances.

Selecting a reputable solar installer is crucial to ensuring the quality and reliability of the system. Homeowners should research potential installers, check references, and obtain multiple quotes before making a decision.

Maximising Solar Self-Consumption

To maximise the benefits of solar self-consumption, homeowners can adopt various strategies. These include optimising energy use during peak sun hours by scheduling high-energy tasks such as laundry and dishwashing, and leveraging battery storage to store excess energy for use during periods of low sunlight or grid outages.

Smart home integration offers additional opportunities for optimising energy usage and enhancing convenience. By connecting solar self-consumption systems with smart home devices and energy management systems, homeowners can monitor and control energy consumption in real-time, further maximising savings and efficiency.
