Metro Manila, 2021 - More and more solar installers promise great savings and reliable performance while ensuring electricity supply during brownouts with hybrid and off-grid solar systems. Even though in other countries these promises may be met, in the Philippines, the bitter truth for consumers often hits hard after 3-5 years of operation. When the solar battery breaks down or has to be exchanged due to loss of charging cycle capacity, or if the savings are not meeting what was forecasted. Since the solar battery itself makes the solar system up to 100% more expensive, the invested money cannot be earned back which leaves consumers with a failed investment and lots of headache.


Furthermore, here are major concerns about solar systems with battery backup in the Philippines:


ENVIRONMENT

Solar batteries and heat don't work well together. Reliable solar batteries are made to perform in temperatures of around 25 degrees Celsius, which we exceed here in the country even on rainy days. Heat causes remarkable efficiency decreases. Moreover, warranty claims are more likely to be rejected if it cannot be proven that recommended temperature levels could not be secured.


FINANCIAL GAIN

When storing 1 kWh of solar (worth PHP 10) in a battery, around 40-70% (worth PHP 4-7) of it will be available to be supplied to your appliances. These efficiency decreases are based on natural and physical losses when storing and converting electricity.


Your overall return on investment with a solar battery would be 8-10 years in the Philippines. However, since you have to exchange and reinvest in a battery after around 5 years, you won’t reach an ROI at all.


It is still best to instead have grid-tied net metering, where solar electricity is sold to your electric provider instead of being stored in a battery, you will be rebated with the generation charge worth P4-6 pesos! Same value but less investment and no maintenance required. With a grid-tied solar system, your return on investment lies between 4-5 years!


BACKUP ENERGY DURING BROWNOUT

Let’s address the promise: "With a solar battery, you will not experience brownouts anymore".


Depending on the capacity, the solar battery will be able to supply a certain amount of electricity required for basic appliances during a brownout. But running aircons or other major electricity consuming appliances won’t work for long, unless you invest in large scale batteries which cost as much as a car. If you truly seek for reliable electricity security during brownouts, it is up to date much smarter to have a generator back up available.


To wrap up, given the circumstances in the Philippines, and the current high pricing and heat sensitivity of reliable solar batteries, a grid-tied solar system with net metering is the only recommendation a professional solar company can give to consumers that aim to save on electricity by looking at an attractive investment in solar energy.
