What is a residential energy storage solution?

Our residential energy storage solution covers 3 ~ 20 kW, and this range is predominantly designed for PV self-consumption, back-up power, load shifting and off-grid solutions for household applications. Storing renewable energy with AlphaESS - it's a no-brainer.

How much does a 2.5kW Solar System cost?

When considering a 2.5kW solar system, one of the crucial factors to consider is the price. On average, the cost for this solar system is around $5,000. However, it is important to note that solar panel prices have come down substantially over the past decade, making it an increasingly affordable option for many.

How much does a residential energy storage system cost?

The cost components of the most common residential energy storage system are as follows: Battery: Depend on the type (e.g., lithium-ion, lead-acid), capacity (measured in kWh), and quality. Inverter: Depend on the capacity and features, ranging from $1,000 to $3,000 or more.

How much money can a 2.5kW solar system save?

A 2.5kW solar system can save you up to $776 per year. Over the panel’s lifetime of 25 years, this adds up to savings of $19,391. The rising cost of electricity has become a cause of concern for many households. Over the past 40 years, electricity prices in the United States have increased by a staggering 270%.

What are the different types of residential energy storage systems?

There are several types of residential energy storage systems, each with its own advantages and disadvantages. The primary types include battery-based, thermal, mechanical, hydrogen energy storage, and supercapacitors. Among these, battery-based systems are the most commonly used for residential energy storage.

Can a 2.5kW Solar System be paired with a battery?

For those looking to have a backup power source, a 2.5kW solar system can be paired with batteries. Two commonly used battery types are lead-acid and lithium polymer. Using lead-acid batteries, the sizing calculation would be: 2.5kWh x 2 (for 50% depth of discharge) x 1.2 (inefficiency factor) = 30kWh.
