One of the most significant advantages of a 5kW solar system is its ability to save you money on electricity bills. On average, this system can save you up to $1,551 per year. Over the 25-year lifetime of the solar panels, the total savings can amount to an impressive $38,781.
The rising cost of electricity is a major concern for many homeowners. Over the past 40 years, the cost of electricity has increased by a staggering 270%. This upward trend is depicted in the following graph:
By installing a 5kW solar system, you can significantly reduce your reliance on utility companies and mitigate the impact of rising electricity costs. The more self-generated electricity you consume, the less you have to pay to utility companies.
Furthermore, the excess electricity that your 5kW solar system generates can be sold back to the grid. As a result, you can potentially earn a 20% return on your investment per year, based on current electricity costs.
The typical cost for a 5kW solar system is around $10,000, making it a cost-effective option for homeowners seeking to transition to renewable energy. It is worth noting that prices for solar systems have significantly declined over the past decade, making them more accessible to a larger audience.
In some cases, homeowners may opt for a 5kW system with battery backup to ensure continuous power supply even during grid outages. When choosing a battery type, it is crucial to consider lead acid vs lithium polymer batteries.
Based on calculations, a lead acid battery system with a 5kWh capacity would require two batteries (50% depth of discharge) and an inefficiency factor of 1.2, resulting in a total capacity of 60 kWh.
On the other hand, a lithium polymer battery system with the same 5kWh capacity would only require one battery (80% depth of discharge) and an inefficiency factor of 1.05, resulting in a total capacity of 32 kWh. Therefore, lithium batteries are highly recommended as they require fewer batteries, reducing both cost and space requirements.
For those seeking to disconnect entirely from the grid, a 5kW off-grid solar system is an alternative worth considering. To achieve a self-sufficient off-grid setup, you would need to purchase 17 or more panels and approximately 32 kWh worth of lithium polymer batteries to ensure a full cycle. The typical cost of batteries required to run a 5kW off-grid system is approximately $14,805.
Considering that each panel occupies approximately 17 square feet, the total footprint of a 5kW solar system with 17 panels would be around 283 square feet. It is essential to consider available space when planning for the installation of solar panels.
On average, a 5kW solar system can generate approximately 25 kWh of electricity per day. This output is based on the assumption that the panels receive a minimum of 5 hours of sunlight. Over the course of a month, this equates to approximately 750 kWh, and over a year, it reaches approximately 9,125 kWh.
The number of batteries required for a 5kWh solar panel system depends on the battery type and its capacity. If using the recommended lithium polymer batteries, you would need approximately 32 kWh worth of batteries. It is possible to opt for a single battery system or connect several batteries of smaller sizes together to meet your energy storage needs.
Considering the potential savings and returns on investment, a 5kW solar system is undoubtedly worth considering. In locations with ample sunlight, you can generate approximately $1,551 worth of electricity each year. This figure represents a 20% return on investment based on the current cost of panels, which is approximately $10,000 for a 5kW system. Investing in solar energy not only helps the environment but also has the potential to yield significant long-term financial benefits.
