Many families are concerned about Should I install solar power? or not? Depending on the needs and financial conditions, households can consider installing to maximize the benefits that solar energy brings. Below are important reasons why every family should invest in this system.
1. What is solar power for households?
Solar power systems for households operate by using photovoltaic panels to collect sunlight and convert it into electricity for daily use.
Depending on their needs, families can choose between a grid-connected system, which connects to the national grid, or an independent system with battery storage, suitable for areas without grid electricity. This is a cost-effective solution, contributing to environmental protection, and bringing long-term economic benefits.
2. Should I install solar power for my home?
The answer is definitely YES. Nowadays, the cost of installing solar power systems has become more reasonable thanks to increasingly improved technology, helping to improve efficiency and prolong the life of solar panels. In addition, this system brings many practical benefits, from saving electricity costs to contributing to environmental protection. Therefore, investing in installing solar power for the family is a right decision and should be done early.
3. Top 8 reasons to install solar power for your home
3.1. Help households save electricity bills
Installing a solar power system helps households cut 50-90% of their monthly electricity bills, especially effective for households using many power-consuming devices such as air conditioners, induction cookers, and washing machines. As electricity prices increase, solar power helps you stabilize costs and avoid escalating bills.
For example: A 5kWp system can help save from 1,5 - 2 million VND/month, equivalent to 18 - 24 million VND/year.
3.2. Quick return on investment, long-term savings
After only about 3-5 years, the solar power system has helped the homeowner recover the entire investment capital, and then can use free electricity for the next 20 years.
With an average lifespan of 25-30 years, the total savings can amount to hundreds of millions of dong.
Expected costs and profits:
- Initial investment cost: 50 - 90 million VND (5kWp system).
- Electricity savings per year: 18 - 24 million VND.
- Payback in 3 - 5 years, then free electricity.
3.3. Take advantage of abundant renewable energy sources
The sun is a free, endless source of energy, unaffected by energy crises or electricity price fluctuations. Vietnam has about 2.000 - 2.500 hours of sunshine per year, creating ideal conditions for effective exploitation of solar power.
3.4. Generate additional income from selling electricity to EVN
If the amount of electricity produced exceeds your needs, you can sell the excess back to EVN, creating additional income each month.
For example: A 5kWp system can have a surplus of 300 - 500 kWh/month, with a selling price of about 1.000 VND/kWh (depending on current policy), helping the homeowner earn from 300.000 - 500.000 VND/month.
3.5. Proactive power source, limit interruption of daily life
During peak season, grid overload often leads to rolling blackouts.
Solar power systems help households reduce their dependence on grid electricity, especially if combined with battery storage, which can provide electricity at night or during power outages.
3.6. Contribute to environmental protection
Solar power helps to significantly reduce CO₂ emissions, limiting negative impacts on the environment.
Every 1kWp of solar installed can save around 1,5 tonnes of CO₂ per year.
If 10.000 households use solar power, they will reduce 15.000 tons of CO₂ each year, equivalent to planting millions of trees.
3.7. Modern technology, simple operation
- Automatic operation: When there is sunlight, the system will automatically generate electricity.
- Monitor via app: You can track the amount of electricity generated and consumed right on your phone.
- Easy maintenance: If installed properly, rain showers will help clean the dust on the panels. However, cleaning 1-2 times/year will help the system operate more effectively.
3.8. Increase the value of the house, demonstrate modern lifestyle
Installing a solar power system not only saves costs but also shows the homeowner's concern for the environment and technology.
A house using renewable energy will become a Smart Home, both environmentally friendly and improving the standard of living.
4. How much does it cost to install solar power for a home?
The cost of installing a solar power system depends on many factors such as system capacity, accompanying equipment and construction costs. Therefore, the specific price will vary depending on your electricity needs and the type of equipment you choose.
Currently, with a conventional grid-connected solar power system, the price ranges from 11 - 15 million VND/kWp.
For grid-connected systems with storage – integrated with a backup battery to provide electricity at night or during power outages – the cost will be higher, ranging from 20 - 25 million VND/kWp. Specifically:
- A 3kWp system can cost from 80 - 90 million VND.
- The 5 - 10kWp system has an estimated price of 100 - 250 million VND.
Because installation costs depend on many other factors, to get the most accurate figure, you should contact solar power suppliers directly for advice and detailed quotes.
5. What capacity solar power system should households install?
The capacity of the solar power system to be installed will depend on the monthly electricity consumption of the family. Based on the electricity bill, you can calculate the average daily electricity consumption to choose the appropriate capacity.
For example, if a household uses about 400 kWh/month (equivalent to 13 kWh/day), a 3 kWp system would be the right choice. Because each 1 kWp can produce 4 - 5 kWh/day, a 3 kWp system will generate 12 - 15 kWh/day, well meeting the electricity demand.
Normally, the electricity bill of households fluctuates around 2 million VND/month:
- If your electricity cost is less than 2 million VND/month, you should install a 5 kWp system.
- If the electricity cost is over 2 million VND/month, you should choose a system with a capacity of 5 - 10 kWp to ensure enough electricity for use and optimize long-term costs.
6. Conclusion
Job Should I install solar power? Whether or not to use solar power depends on each family's electricity needs, financial capacity and desire to save long-term costs. Installing solar power helps reduce electricity bills, take advantage of clean energy and increase autonomy. Although the initial cost is high, after only 3 - 5 years, the system can recover capital and be used for free for 25 - 30 years. Depending on the needs, the family can choose the appropriate capacity to optimize efficiency. Follow now Green In to learn more about solar energy.
