Frequently Asked Questions
What information do I need for a complete solar lighting design?
To complete a solar lighting setup, some information needs to be gathered. This includes data such as operation requirements (e.g., dusk to dawn, dimming, motion sensing, etc.).
We also need data points such as light level or lumen output requirements to ensure we are providing the required light output.
Finally, the project location is needed so we can determine the availability of sunlight and the length of night to correctly size the solar power assembly to operate the light as needed.
What is the lifespan of a SolarRatio solar lighting system?
All of our solar lighting systems are designed to operate in the field for 25+ years with minimal maintenance. The only component that requires regular maintenance is the battery, which is replaced every 5+ years.
All other components have a lifespan of 15 or more years with the solar panel life of 25 or more years.
The batteries are also fully recyclable and non-hazardous unlike the batteries from many other solar lighting systems on the market.
Where are the prices for the SolarRatio solar lighting system?
We do not list our prices because each of our systems is uniquely crafted to fulfill specific project requirements. Rather than offering a generic solution, we deliver a solar lighting system tailored to meet all necessary criteria and appropriately sized for optimal performance at the installation site.
Can I use the SolarRatio to retrofit my existing lights?
The response is two-part. Yes, the SolarRatio is designed to reach the same brightness levels as traditional electric lighting. However, the existing poles and foundations cannot be reused. The solar power assembly adds considerable weight and EPA that standard light poles are not built to support. Thus, the poles are replaced to ensure structural integrity for the solar lighting system.
Does the SolarRatio come with Smart Controls?
Yes, we offer control options that can be managed via Bluetooth or WiFi. These are particularly beneficial when you need to oversee a large number of systems or when the system is situated in a very remote area.
However, smart controls are not always necessary; they are often complicated accessories that go unused. Most standard solar lights simply need controls to switch the system on and off, and nothing beyond that.
Talk to your solar lighting specialist about the various options available and see if a smart controller would be a good fit.
Will the SolarRatio work in extreme weather conditions?
Yes, the SolarRatio system operates in extreme weather conditions. Our systems are designed with a minimum of five nights backup, meet wind load ratings of 180+ MPH wind loads, utilize marine grade aluminum with stainless steel fasteners for coastal and salty climates, and our batteries perform to -40° c/f, ensuring that your light will operate no matter what conditions are thrown at it.
