The lights turn off, and the aircons and electric fans stop working. Yes, it’s a brownout. What happens to your solar energy system during a power outage?
As what the name says, grid tie systems are interconnected to your utility – otherwise referred to as the grid. In short, grid tie solar power systems are solar systems that are tied to the grid. With this system, you use solar as the first priority power during daytime.
The grid tie system is the most popular and most highly recommended solar system for areas with stable grid power such as the Metro Manila. These grid tie systems do not have batteries or power storage. They do not work during nighttime and brownouts. However, they are relatively cheaper because they don’t come with batteries. Thus, return of investment is faster, usually between three to five years. To keep it simple, with a grid tie solar system, you make your money back within 5 years. For the next 20 years, you profit from your system. Definitely a win-win.
Now, what happens to a grid tie system during a brownout?
During a power outage, even if the sun is out, your grid tie system will automatically shut down as it is interconnected to the grid and must closely follow its regulations. This is a safety measure to prevent your solar system from exporting power, or to prevent the system from accidentally electrocuting the line men that may work on and fix the power lines. Thus, grid tie systems are strictly required to automatically shut down when the power is out.
Hybrid and Off-Grid Systems
Off-grid systems, on the other hand, is completely independent from the grid and works with whatever you sow from your solar panels. This type of system is recommended for areas with unstable grid supply or where power outages are very frequent. The power generated from your system is stored into batteries which makes it operational even during brownouts.
A hybrid system is a combination of a grid tie and an off-grid system. Hybrid setups allows users to have complete control and flexibility on the energy harvested by their solar panels. They can either opt to store power in the batteries or sell it back to the grid. This system works even during brownouts and is the best choice for clients who want energy security and independence 24/7.
Due to the limited lifespan of a battery, you will need to replace if after about five years. Batteries serve as the energy storage component of the system, and are also relatively high in terms of cost. Hence, the off-grid and hybrid solar setups cost more compared to grid tie systems, and have longer ROIs.
