Upkeep and Benefits Over Time of Solar Energy​

Many people hesitate to switch to solar energy because they worry that the effort required will not be worth the benefits. However, the facts show that solar energy is a long-term investment with minimal maintenance, providing various benefits over time.

​

Maintenance Requirements: Minimal and Easy to Do

Solar panels are known for their very low maintenance requirements. Since they have no moving parts, the risk of mechanical failure is minimal. The routine maintenance required typically involves cleaning and inspecting the panels 2–4 times a year to keep them in optimal condition. In addition to that, rainwater can also wash down some of the dust on solar panels. According to a report from the International Renewable Energy Agency (IRENA), with this simple maintenance, solar panel efficiency can be maintained for many years. However, it is also important to note that proper cleaning is required when solar panels are exposed to external pollutants such as cement, paint, metal particles, and other severe contamination that can cover the solar panel.

Longevity and Reliability: A Safe Long-Term Investment

Solar panels are generally designed to last a long time, with many manufacturers offering product warranties of around 12 years and performance warranties of up to 25 years. The National Renewable Energy Laboratory (NREL) notes that solar panels typically degrade at a rate of only about 0.5–0.8% per year (depending on the module), meaning that after 25 years, the panels will still be functioning at around 87.5% of their initial capacity. Inverters, which are a crucial component of the system, typically have warranties of 5–10 years.

 

Long-Term Savings: Saving Money in the Future

Installing a solar energy system does require a substantial initial investment, but the long-term savings are significant. On average, a solar panel system can reduce monthly electricity bills by up to 50–75%. These savings can amount to hundreds of millions of rupiah over 20–25 years, depending on location and energy usage. Examples from users in Indonesia who have installed solar panels show that they can reach a break-even point within 5–7 years, after which they enjoy nearly free electricity for the remainder of the solar panel’s lifespan.​
