Space utilization, intermittency, grid integration, and efficiently converting sunlight into electricity are notable roadblocks in the energy sector. Solar cells, which are the primary technology behind photovoltaics, convert light into electricity for power generation. Building-integrated photovoltaics (BIPV) improve space utilization and boost energy efficiency in urban environments. Smart inverters improve the integration of solar energy into the grid.
They stabilize the grid by managing fluctuations in power output and improving energy management. Solar tracking systems adjust the angle of solar panels to follow the sun''s movement and maximize energy capture throughout the day. Further, batteries store excess electricity generated during the day and allow PV systems to supply power when sunlight is not available. Thus, advanced photovoltaics increase generation capacity and effectively support sustainable energy solutions in a rapidly changing climate.
EtaVolt is a Singaporean startup that offers solutions for maximizing the efficiency and longevity of photovoltaic (PV) systems. It utilizes four key technologies, ηMax, ηPod, ηTune, and ηGen. The ηMax solution focuses on effective maintenance by employing an automated regeneration tool to unlock lost performance and improve the power output of solar panels without disassembly. Next, ηPod provides a smart decentralized recycling process, allowing for the profitable recycling of solar panels through mechanical assessments.
This technology avoids harmful chemical treatments and enables on-site deployment of the recycling line. Additionally, ηTune serves as an AI-enabled health checkup tool that uses historical inverter data to pinpoint causes of underperformance. This technology delivers actionable insights to improve solar investments. Lastly, ηGen facilitates quick visualizations and quotes in just three minutes to align the pre-sales process for solar businesses.
Delex Belgium is a Belgian startup that designs and distributes renewable energy solutions, offering solar panels, batteries, and electric car chargers. It serves residential, commercial, and industrial customers with its range of products. Its photovoltaic technology converts sunlight into electricity through mono- and polycrystalline panels. These panels have power capacities ranging from 280 to 350 watts and support grid-connected and off-grid configurations. The photovoltaic kits are easy to install on roofs or floors, with an estimated output of 150 kWh/m² annually.
Grid stability, backup power, energy time-shifting, and maximizing solar utilization are key challenges in the solar energy sector. Solutions like lithium-ion batteries address intermittency by providing quick-response storage for residential and utility-scale solar projects. Besides, flow batteries offer long-duration storage for grid stability and support large-scale solar integration.
In addition, solid-state batteries deliver higher energy density and safety to reduce costs and space requirements for energy storage. Thermal energy storage also collects excess solar energy in the form of heat, which is later converted back into electricity or used for heating purposes. Besides, for long-duration storage options, hydrogen is stored and converted back into electricity or used as a clean fuel.
For self-sustained energy systems, off-grid solar technologies offer effective means to produce electricity without relying on centralized networks. Solutions like photovoltaic panels capture sunlight and convert it into electricity for off-grid systems. In addition, inverters convert the direct power generated by solar panels into alternating power.
Further, to store excess solar energy for use during periods when sunlight is unavailable, lithium-ion, lead-acid, or flow batteries are an effective source of power. Energy management systems (EMS) also monitor and optimize power usage, battery status, and energy generation. Further, charge controllers regulate the flow of electricity from the solar panels to the batteries while preventing overcharging or deep discharge. These solutions enable more reliable, sustainable, and cost-effective off-grid solar power systems.
US-based startup Dragon Q Energy builds an off-grid, solar-integrated power system that brings electricity to underserved communities using its solution, PowerPole. This system features a modular design that allows it to scale according to specific needs while each unit produces around 15 kWh of energy. PowerPole''s construction withstands extreme climates and adverse weather conditions.
This solution is thus functional even in the most remote locations. By burying batteries just beneath the surface, the company uses geothermal cooling for optimal performance. Additionally, the use of a pressurized argon environment reduces fire risk in oxygen-free settings. With its weld-free design, the PowerPole effectively addresses energy scarcity while promoting prosperity and resilience in humanitarian and disaster relief applications.
