Grid-scale battery projects are becoming more and more popular in the UK, since they help balance the supply and demand of electricity in the grid as renewables such as solar and wind are erratic in their supply of power. Several variations on the Sun-4 architecture were subsequently developed and used in later computer systems produced by Sun and other vendors.

Because the sun's rays hit us at different orientations, most people don't know what the best photo protection is for themselves; they are confused and not prepared for that kind of exposure.

Sun-4m Originally a multiprocessor Sun-4 variant, based on the MBus processor module bus introduced in the SPARCserver 600MP series. The _ga cookie, installed by Google Analytics, calculates visitor, session and campaign data and also keeps track of site usage for the site's analytics report.

One of the easiest ways for companies to harness solar power is to make use of under-utilised rooftops by leasing them out.The term Sun-4 continued to be used in an engineering context to identify the basic hardware architecture of all SPARC-based Sun systems. Sun 4/110, 4/150, 4/260 and 4/280 systems upgraded with the Sun 4300 CPU board (as used in the SPARCserver 300 series) were referred to as the 4/310, 4/350, 4/360 and 4/380 respectively. We have built over 45 Megawatts (mWp) of solar capacity to date (enough to power 45,000 homes) and own and manage 22 mWp. The Cray CS6400 was also nominally a Sun-4d machine (sun4d6), although it required a custom version of Solaris. Since 2009 solar power has become a recognised source of cheap, reliable, long-term power leading to a huge expansion in its use.
