Usually the equipment will be used for multiple purpose and universities always look for a flexible
manufacturer and products which can provide variety features in one box.
Also they look for a product which can be expanded in future.
The great thing about solar panels is that they do not require a lot of maintenance. However, it is still important to get them checked regularly to ensure safe.
R&D Engineers usually need higher end equipment to be able to design robust products. They like to have an universal product in one box so they do not have to buy multiple units. Space is also a concern in R&D laboratories.
Test Engineers are an important chain of the product development to discover potential defects and potential specification difference. They like to have an equipment to be able to perform all critical tests. Easy to use, reliable and Flexible.
In production the key concern is the cost. The unit does not need usually higher end specification. Since production could run 24/7 and downtime is not accepted maintenance must be easy and quick.
Battery materials include Cathode, Anode Materials, Casing Materials, Battery Current Collectors, Conducive Materials, Graphene and Graphite Oxide, and Binders.
A solar charge controller manages the power going into the battery bank from the solar array. It ensures that the deep cycle batteries are not overcharged.
