Solar
Energy Harvesting

Do you want your device to recharge from a solar (photovoltaic) source without the need to change the battery? Then, discover our photovoltaic Ambient Energy Manager which is capable of harvesting energy even in low-light conditions

Is solar energy harvesting for you?

Let’s assume you develop a battery-powered loT wireless device that
operates under light sources: sun,
light, bulb, tube, etc.

You (or you customers) need to re-place the batteries of these devices, because they run out of energy. This generates operational costs and a negative impact on environment

Depending on the lightning conditions (low-light indoor conditions to sunny outdoor conditions), PV cells can generate from 10 µW to 10 mW per cm² , most likely enough to power your device

When properly selected (material and topology) and sized (illuminated area), a PV cell combined with our state-of-the-art solar energy harvesting AEMs will recharge the batteries of your loT application from ambient light. Using e-peas’ solar energy harvesting, you will avoid typical operating associated with battery replacement. By using e-peas’ Ambient Energy Manager, you will avoid battery replacement and enable more features to your devices
