How Long is the Optimal Life of Solar Panels?

Solar panels have become an increasingly popular solution for providing renewable energy for residential, industrial and even remote installations. However, when considering investing in solar panels, one question that often arises is How Long is the Optimal Life of Solar Panels?

Optimal Life of Solar Panels

The optimal life of solar panels before they need significant replacement or repair refers to the period of time during which the panels can produce energy efficiently and their operational costs are paid for. In general, solar panels are designed to last a long time, with an optimal operational life span of around 25 years.

However, certain factors can affect the optimal life span. Here are the factors that affect the optimal life span of solar panels:

1. Material Quality:

The quality of the materials used in the manufacture of solar panels can affect their operational life. High-quality solar panels tend to be more durable and maintain their energy efficiency for longer.

2. Maintenance:

Proper maintenance can extend the operational life of solar panels. This includes regular cleaning of the panels and monitoring to ensure there is no significant damage or wear.

3. Location and Environment:

The environment around the solar panels can also affect their operational life. For example, solar panels that are exposed to direct sunlight will tend to have a longer operational life than those that are frequently exposed to extreme weather or pollution.

4. Latest Technology:

Advances in solar panel technology can extend the operational life and increase their efficiency. Newer solar panels often have features that improve their durability and performance over time.

Economic Considerations

Although solar panels are designed to last a long time, owners must consider the economic aspects of the investment. The initial cost of purchasing and installing solar panels must be compared to the potential energy savings that will be generated over the operational life of the panels. In many cases, the initial investment costs can be paid off in the first few years, and solar panels can continue to produce energy with minimal operational costs thereafter. Indirectly, installing solar panels can save users up to 30% of their electricity consumption.

So it can be concluded that …

The optimal life of solar panels is an important factor to consider when deciding to install a solar panel system. With proper maintenance, solar panels can last a long time and provide sustainable renewable energy benefits for years to come. With technology continuing to advance, the operational life of solar panels can be extended even further in the future, making them an attractive investment for the future.

“Jupiter Rahayu” Food Garden, a Manifestation of Sei’s Commitment to the Environment

As a form of corporate responsibility towards society and the environment, SEI supports the urban farming movement, this is the Jupiter Rahayu Food Garden which is a form of integrated urban farming.

Transforming one of the empty lands into a productive land that is able to answer the challenges related to food security which is also able to increase the welfare of the surrounding community. Jupiter Rahayu Food Garden not only focuses on plantation businesses but also explores livestock businesses such as catfish and laying hens. As an effort to maintain the environmental ecosystem, the surrounding community is also equipped with the ability to manage household waste through Lodong Sesa Dapur (Loseda) and compost bin facilities which will then change household waste into compost fertilizer used in the Food Garden area.

In line with the company's business, Kebun Pangan Jupiter Rahayu is also equipped with a "Saung Tenaga Surya" facility which is often used as a gathering area for residents. With Saung Tenaga Surya, Kebun Pangan Jupiter Rahayu has quite complete lighting with charging facilities in its Saung.

The development of the Jupiter Rahayu Food Garden is considered significant, especially by the SEI Corporate Communication Team, which always accompanies the process of change. The program, which is a special concern of SEI's President Director, I Made Sandika Dwiantara, is one of SEI's leading CSR programs in 2024.

The enthusiasm and perseverance of the Jupiter Rahayu Food Garden activist community finally bore sweet fruit. Recently, the Jupiter Rahayu Food Garden has entered the harvest period and has succeeded in collecting 30 kg of red onions and 36.5 kg of corn…WOW!!

Starting from the success of the harvest period, the SEI Corporate Communication Team strives to support the big dream of the Jupiter Rahayu Food Garden to be better known by the wider community, not only by name but also by the harvest results that can be felt by other communities outside the Jupiter Rahayu Food Garden Area. So the Workshop and Sharing Session activity was initiated with the theme "Digital Branding to Support Urban Farming Business Activities" which on that occasion all the people who attended received brief knowledge about the SEI Solar Panel such as its benefits, how it works and maintenance efforts.

The enthusiasm of the community is what will make the Jupiter Rahayu Food Garden even more "fragrant", the Jupiter Rahayu Food Garden can be a comprehensive educational medium that will support learning in schools. Hopefully the presence of SEI in the Jupiter Rahayu Food Garden program can provide maximum benefits and can motivate its activists to always be active and productive in its management. **

World Solar Day and SEI’s Important Role in Sustainable Development

Solar Day is one of the commemoration days that is rarely known by the public. World Solar Day is commemorated every May 3rd every year. The commemoration of Solar Day is a form of campaign for solar energy which is an environmentally friendly and renewable energy.

The commemoration of World Solar Day began with a campaign for the use of environmentally friendly energy which was first initiated on April 22, 1970, coinciding with the first Earth Day initiated by an environmentalist and solar energy observer from the United States named Denis Hayes.

SEI Builds Rooftop Solar Power Plants at 3 International Airports to Support Green Energy in Aviation Industry

PT Surya Energi Indotama (SEI) has once again demonstrated its consistency in supporting the use of green energy or New Renewable Energy (EBT) in Indonesia. As an energy company in Indonesia, SEI has built Rooftop Solar Power Plants (PLTS) at 3 PT Angkasa Pura II International Airports, namely Soekarno Hatta Cengkareng Airport, Kualanamu Medan, and Banyuwangi. The signing of the cooperation agreement was carried out on November 26, 2021 with a target completion of construction at the end of 2022. This cooperation is a real step from the 3 main stakeholders in the construction of PLTS, namely PT Angkasa Pura II, SEI, and PT Pertamina Power Indonesia (PPI).

This development is also a realization of the energy transition towards renewable energy with a target capacity of 26.3 MWp in 2025 at 20 airports of PT Angkasa Pura II. The development is in line with the Global Net Zero Carbon Emissions program in 2050 initiated by the Airport Council International (ACI) and received support at the 41st Assembly of the International Civil Aviation Organization (ICAO) which took place on September 27 - October 4, 2022 in Montreal, Canada. This is the initial step for PT Angkasa Pura II to achieve the energy mix target in the aviation industry that has been planned.

The total capacity of the PLTS at the 3 airports is 2.39 MWp. Each consists of 1.5 MWp at Soekarno Hatta Airport, 862 kWp at Kualanamu Airport, and 35 kWp at Banyuwangi Airport. SEI acts as the implementing contractor in collaboration with PPI to fund the construction of PLTS at the 3 airports.

The construction of Rooftop Solar Power Plants (PLTS) at Banyuwangi Airport, Kualanamu Airport, and Soekarno Hatta Airport has now been 100% completed. In addition to direct contributions to the transition to new renewable energy, PLTS at these 3 airports are also exhibited as a portfolio that Indonesia has implemented clean energy in the Aviation sector through Rooftop PLTS installed at airports. The public can see it directly from the plane when landing or taking off.

This Rooftop PLTS is targeted to be able to produce 58.8 GWh of energy during its operation for the next 20 years. This positive impact is expected to be a guardian of hope to achieve Net Zero Carbon Emission by 2050 in the aviation sector, as well as a benchmark for implementing green airport concepts.

G20 and Energy Transition

The grand G20 Bali event in June-November 2022 was successfully implemented. An achievement was made with the presence of 17 heads of state participating in the summit amidst the difficult world situation. The G20 members are South Africa, the United States, Saudi Arabia, Argentina, Australia, Brazil, India, Indonesia, the United Kingdom, Italy, Japan, Germany, Canada, South Korea, Mexico, France, Russia, China, Turkey, and the European Union.

In this summit, various concrete results were agreed upon as solutions to various global issues. One of them is the sustainable energy transition. The sustainable energy transition is one of the priority issues in the G20 Summit because it is part of the key solution to overcoming the ongoing global energy crisis.

Participating countries agreed to accelerate the energy transition, including ensuring the achievement of the global sustainable development target by 2030. Especially for access to reliable, sustainable, and affordable modern energy for all. As is currently known, the sustainable energy transition has a very important role in global climate change.

The G20 Bali Summit emphasized the importance of developing innovative and affordable technology and infrastructure. This aims to support the energy transition, including the importance of cooperation on knowledge transfer and technological innovation. In addition, the agreement continues to increase mutual investment and encourage financial flows to developing countries to accelerate the energy transition and strengthen cooperation.

The acceleration of the energy transition is based on the principle of considering the benefits for all parties without anyone being left behind in the process. These principles are:

1. Strengthening trust and clarity in planning, implementation and evaluation nationally
2. Improving energy security, market stability and affordability
3. Securing energy supply and infrastructure
4. Securing resilient, sustainable and reliable systems
5. Improving the implementation of energy efficiency
6. Diversifying energy systems and mix
7. Reducing emissions from all energy sources

In addition, the challenges that need to be faced are funding issues in addition to technical issues such as mastery of technology, project implementation time, and the readiness of the supporting industry. The energy transition requires a lot of funds, including to accelerate the retirement of the Steam Power Plant (PLTU). In overcoming these challenges, Indonesia is trying to make a number of breakthroughs, including the issuance of Presidential Regulation Number 112 of 2022 concerning the Acceleration of Renewable Energy Development for Electricity Supply. With the presence of the G20, this is a strengthening of Indonesia's and the world's commitment to realizing a better world by accelerating the energy transition process towards clean and new renewable energy.
