An onsite PPA enables a company to obtain a reliable supply of green electricity, decoupled from the energy markets - and with no initial investment. Known as distributed generation or on-site power generation, this approach allows organizations to offset grid costs, manage peak demand, and gain greater energy independence. But what exactly is on-site power generation, and how does it work? Let's dive into the world of energy. In this article, you will learn more about so-called onsite PPAs and read why photovoltaics is a key technology in this context.

In summary, solar energy is a more eco-friendly and cost-effective option than thermal power due to its smaller environmental impact, abundant resources, and reduced greenhouse gas emissions. Solar energy converts sunlight into electricity through photovoltaic cells or solar thermal systems. Its main advantages include zero emissions and solar costs are now well below those of new coal and natural gas plants. The key drawback is intermittency — no generation at night — and upfront. An alternative to PV is solar thermal panels: as opposed to PV generating electricity, thermal panels create heat. When installed on a roof facing the sun, they capture the hot sun rays which are used to heat water stored in a cylinder. Cost Savings: Reduces energy bills, especially for heating applications, and can have a quick payback period in sunny regions.

Key Factors for Selection: Consider capacity (kWh), depth of discharge (DoD), efficiency (80-90%), and expected lifespan when choosing a suitable battery for your solar energy needs.
Factors like battery size, power rating, roundtrip efficiency, lifetime, and safety are crucial when choosing a solar battery. Lead-acid batteries are common but have lower capacities and shorter lifespans compared to lithium-ion batteries, which offer higher efficiency and longer lifetimes despite being more expensive.
Suppose you consume 30 kWh daily. If you choose a lithium-ion battery with a usable capacity of 10 kWh and a DoD of 90%, you'll need at least three batteries to meet your daily needs. By understanding these components, you'll be equipped to choose the right size battery for your solar energy system, ensuring seamless and efficient operation.
