http://www.solar.org.il has over 1,000 Link Juice Leaks.
here is a typical sample
The link to "http://www.solar.org.il/services/%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD-%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD-%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD.html" has resulted in HTTP redirection to "http://www.solar.org.il/404.html".
something wrong there.
The is also a few canonical isses, pages blocked by robots, if you really have to block them, use a meta noindex,follow tag, so thsat the link juice will still flow.
50+ broken links, each one leaking link juice, example
The Web page contains the broken link 'http://www.solar.org.il/articles/search/.html'.
This site has 1,0000+ brokrn links, leaking link juice
The Web page contains the broken link 'http://www.solar-israel.co.il/investing-in-green-energy'
heaps of html errors, an example
The page at "http://www.solar-israel.co.il/" contains invalid markup.
The Tag 'p' was not closed correctly, the Tag 'div' was closed instead.
Both sites have many other issues in smaller numbers.
I dont know what suite os yours, but who very fixes all their leaks should out do the other.
