What are the different models of solar batteries?
1. The open-lead solar battery
The open lead-acid solar battery costs between Php 9,123 and Php 24,329.
This battery is used by second homes, isolated sites, and public establishments. It has a lifespan of 3 to 4 years and benefits from a number of cycles between 300 and 500. It has a discharge depth of 50 and 80% and withstands temperatures from -5 to 30°C.
This type of battery must be placed in a ventilated area since it emits hydrogen. Its voltage is between 2 to 12V. The storage capacity varies from 10 to 50 Ah for standard models, and up to 120 Ah, or even more, for specific models.
The open lead acid battery can only be used occasionally. Some manufacturers offer high-performance models adapted to total electric autonomy.
2. The AGM solar battery
The AGM solar battery sells between Php 18,247.19 and Php 42,576.78.
This model is used in measuring stations and lighting companies. It is suitable for motor power applications of electrical appliances such as vehicles, thrusters, or fridge freezers. Its lifespan is 6 to 8 years, with a number of cycles between 500 and 900. This battery has a storage capacity of 70 to 100 Ah for 2 to 6V models and up to 200 Ah for 12V models.
This type of battery resists temperatures between -10 and 50°C, has an 80% discharge depth, and is resistant to shock and vibration. The AGM solar battery is highly safe because it releases little hydrogen and has no electrolyte leaks. It is also unique in that it does not require maintenance.
3. The gel solar battery
A gel solar battery costs between Php 30,411 and Php 121,647.
It is used to power water treatment systems or to power meteorological and seismic monitoring devices. Its lifespan is estimated between 8 and 12 years, with a number of cycles of 800 to 1500. The battery withstands temperatures between -20 and 70°C. It is also shock resistant and benefits from a 50% depth of discharge. 2 to 6V models store between 150 and 250 Ah, and up to 400 Ah for 12V batteries. Some manufacturers offer high-performance gel solar batteries with a storage capacity of 450 to 600 Ah.
The latter requires the use of a solar regulator in order to preserve the performance of the device during voltage variations.
4. The OPzV solar battery
An OPzV solar battery is worth between Php 60,823 and Php 243,295
This battery is suitable for frequent charge and discharge applications and is used as a power device for emergency generators, telephone booths, or security systems. It has a number of cycles from 1200 to 2000.
Its lifespan varies from 10 to 15 years depending on use. The nominal storage capacity of 2 to 6V models is estimated between 300 and 700 Ah, and up to 850 Ah for 12V models. Some 48V models available on the market store up to 1000 Ah and are suitable for powering buildings or establishments open to the public. Their discharge depth is 80%.
OPzV batteries require no maintenance and are resistant to temperatures between -30 and 80°C.
5. The lithium solar battery
A lithium solar battery costs between Php 91,235 and Php 304,119
This model is used for applications requiring high electrical power, such as powering industrial machinery, weighbridges, or boats. A lithium solar battery has a 90% discharge depth. It resists temperatures between -10 and 70°C. It benefits from 1500 to 3000 cycles and has a longevity of +/—20 years. Some manufacturers offer models with a cycle duration of 6000.
This model resists partial or prolonged discharges. Battery models from 2 to 6V have a storage capacity of 400 to 900 Ah, and the 12 to 40V models have a storage capacity of 2500 to 3000 Ah. A solar lithium battery has high waterproofness and humidity resistance of 95% RH.
How to choose a solar battery?
The choice of a solar battery is made based on a few criteria:
1. Storage capacity
- Solar batteries with a storage capacity between 10 and 500 Ah are suitable for applications lasting 3 to 5 days without recharging.
- Models with a capacity of 600 to 1000 Ah are used to power installations for 7 to 10 days.
The batteries are also mounted in parallel or in series, thus increasing the storage capacity and voltage of the device.
2. The tension
The voltage of a solar battery must correspond to the power of the installations:
- A 2 to 6V battery: It is suitable for lighting applications or the electrification of fences.
- A 12V battery: It is used to power water pumps, inverters, or 800 W photovoltaic installations.
- A 24V battery: It can power homes, stations, and telephone booths.
- A 48V battery: It is suitable for powering boats, motorhomes, and buildings.
